Working toward a better future for humankind, Solec creates products that convert the sun's energy into electric power.
Since 1967 Solec solar electric modules have been used worldwide in urban and remote locations. From major metropolitan areas to small villages, Solec's cost effective modules work dependably and efficiently.
In 1994, Solec combined forces with SANYO Electric, Japan. Both companies share a commitment to excellence and making strides toward improvements in the solar energy industry. These are exemplified by the numerous patents held by the companies and proprietary advances that have been made. Further, in our efforts to manufacture a superior product, Solec's modern equipment uses high quality materials.
Solec was a pioneer in developing major improvements in crystalline silicon photovoltaic (PV) technology. Today nearly all high-power PV applications utilize crystalline silicon single crystal cells and photovoltaic modules.
In 1997, SANYO introduced a product called HIT Power 21™ (Heterojunction with Intrinsic Thin layer). This 21st century hybrid product combines the single crystalline cell with amorphous silicon. The result has been astounding. The HIT™ cells have the capability of achieving an incredible 20% efficiency rating.
At Solec, we continue to find ways to harness the energy of sun to provide alternative energy. Our goal is to preserve our environment by bringing the sun down to earth.

Semi-crystalline silicon Ribbon and Amorphous Thin Film in Germany
Thin-film Technology Thin-film technology involves fixing an active semiconductor film on to the carrier medium (substrate). The natural semiconductor silicon is the most suitable for thin-film technology. Amorphous silicon has no crystalline structure and so can be vaporized in ultra thin films on glass, for example.
The SCHOTT Solar ASI material (ASI stands for amorphous silicon) has a thickness of less than 1 micrometer. This means that only approximately one gram of semiconductor per square meter of substrate is needed to coat a pane of glass. SCHOTT Solar ASI® glass is manufactured at Putzbrunn near München. Here, amorphous silicon is deposited on glass panels. For this, plasma is created in a high-vacuum reactor and from this silicon can be deposited on the surface of the glass. A fine laser is used to structure the silicon in such a way as to produce a large number of tiny solar cells. Transparent conductor pathways conduct electrons to the module’s cables. Several modules are connected in series and linked to the inverter. The direct current produced is converted here into 60 Hertz 220 volt alternating current and fed into the power grid.
Crystalline Technology In crystalline solar technology, the roughly 0.3 mm thick wafers made of the semiconductor material silicon are further processed to ensure that sunlight hitting them can be converted directly into solar power (solar cell). To make this power accessible for use, a number of these solar cells are series-connected to make up what is known as series strings. The solar cells connected in series in this way need to be protected for many years from the effects of the weather. This is why they are ‘packaged’ together in modules. On the sunward side the cells are protected by a highly transparent solar glass pane, whereas the underside takes the form of an insulating film or - as in ASE-300-DG modules, a second pane of glass. A connection socket picks up the direct current generated. Several modules are connected together via cables, which link them to the inverter. The direct current produced is converted here into 60 Hertz 220 volt alternating current and then fed into the power grid.
SCHOTT Solar uses a patented process for manufacturing the wafers known as the EFG process. This process differs from the conventional method in that the thin silicon wafers are not sawn by wire saws from a block but are drawn directly as silicon film from a silicon furnace. To ensure process stability, the silicon film is produced in the form of an octagonal hollow pipe. In the EFG process, the silicon film already has the required thickness of roughly 0.3 mm. The last step in the process is to separate the wafers from the surface shell of this hollow pipe using a laser.
Since the wire is about as thick as the wafer itself the conventional wire sawing process leads to material losses of up to 50%. In the EFG process, however, only about 10% of the silicon material is cut away, and some of this can be recycled. This makes EFG considerably lighter on resource use and more efficient than other processes.

BP Solar

| Rank | 7 | 3 |
| Sales (MW) | 86 | 85 |
| Country | Maryland | Frederick |
| Technology | Mono & Multi | Crystaline si |
Both Mono and Multichrystalline located in Frederick, Maryland
BP Solar has four major manufacturing plants in Spain (Madrid), Australia (Sydney), USA (Frederick) and India (Bangalore). With currently more than 90 MW of capacity it is our aim to more than double our current production capacity to 200MW by the end of 2006. BP Solar USA is the nation's largest fully-integrated solar power plant
BP Solar has approximately 550 employees at its Frederick headquarters, said spokeswoman Sarah Howell. In November, the company announced a 140,000-square-foot, $70 million expansion project that is expected to add 70 new jobs in the area, she said, and double the plant’s manufacturing capacity.
BP Solar's high performance MultiCrystalline product line includes our most popular BP 3160, SX 170 and BP 175 products. All our MultiCrystalline products feature our advanced silicon nitride MultiCrystalline cell technology
In its latest move, the company has developed a solar module--a collection of solar cells--using a new silicon-manufacturing approach that the company says drives down the cost of generating solar power. The new technology boosts power production 8 percent without a price increase, the company says. BP Solar will begin production of these modules by mid 2007.
Lee Edwards: Over the next 10 years, BP Solar believes that a silicon-based cell technology will continue to drive cost efficiency. This announcement of the Mono2 approach to creating the silicon wafer was driven by an acknowledgement of the two different types of silicon available: monocrystalline and multicrystalline. Monocrystalline silicon makes for high efficiency, but it's relatively expensive, and the solar-power industry competes with the microprocessor industry for this type of silicon. Multicrystalline is cheaper, but it is lower quality. Mono2, broadly speaking, gives the same electrical-efficiency benefits as monocrystalline wafers but uses a multicrystalline casting approach that is less expensive.
LE: In the traditional multicrystalline manufacturing, you basically put a bunch of rocks in a ceramic crucible, heat it to 1,500 degrees C, let it sit there for a day, and cool it slowly. You get a block of silicon, but the crystal structure is random. Some people say it's more visually appealing because of the way light reflects off it, but each one of those grain boundaries creates a barrier to electron flow. The beauty of our technique is that we've found, in our protected intellectual property, a way to essentially get a single crystal using another approach. The details are proprietary, but it's a combination of metallurgy and the process that allows us to do it. When we say "efficiency," there are two components to it. There are some who love to advertise their cell-conversion efficiency, so you'll see 19 or 20 percent efficiency quoted. That is the amount of sunlight that hits the surface that is converted to electricity. When we talk about efficiency within BP Solar, it is the dollar-per-watt cost to convert sunlight into electricity. The Mono2 module can produce 8 percent more power for the same price as a module made from multicrystalline silicon modules on the market today. This decreases the price per watt.
TR: What other ways are you trying to squeeze extra watts from silicon?
LE: We've got two approaches within BP Solar to do that. One involves grooving the wafer itself with precision lasers that increase the surface area, allowing more sunlight to be converted to electricity. And the other is printing material on the front and the back to create electrical contacts that pull out the electricity without blocking too much sunlight in the process. There are some innovations in the value chain that we're on the front edge of, including how you access your customer. In the U.S. we are selling products in more than 250 Home Depots, in California, New Jersey, and New York. Having in-store solar-sales capability basically simplifies the value chain so you don't have BP Solar selling to a group that sells to another group that goes out and markets the product. There's only the installer in between, and we endorse their capabilities. Another aspect that we're looking at is how you actually construct a frame [for a solar module]. Rather than using extruded aluminum framing, we're looking at a cast polyurethane mold. It's stronger, it's lighter, it's easier to install, and it looks cool. And if you were really into the architecture, you could have different colors, different types of arrays. [Aesthetics] is a big barrier for going mainstream within solar because people don't want to feel like they've got a bunch of screen doors screwed into their roofs. And then the ultimate is if you make the solar as part of the roof, so you bring together building materials with the photovoltaic industry and say, Let's build a new roofing material that's pre-wired for new construction.
At the moment, the solar industry is struggling with a shortage of silicone, the primary raw material to make most of the solar panels in the world.
There's plenty of sand so in the long run it won't be a problem. In the short run, it's the equipment to purify the silicone to 99.59 purity or better. And so in time new capacity will be built and we'll get beyond the shortage, but in the short term, there is not sufficient capacity to meet the growing demand. So what we're doing is working on new techniques to use the silicone we can in a more efficient, more productive way. So as an example: technology to get thinner wafers in the overall construction of a cell. We're now looking at 200 microns and lower where two years ago it was 300 microns and higher. So that's a 30% improvement.
We're also looking at using different grades of silicone at lower costs to apply to solar panels that really has a great breakthrough opportunity. So we've got some now announced technology called Mono Squared, which essentially creates a monocrystal in a solar silicone wafer in a process very similar to multicrystalling, which is lower in cost and faster. And that again will create somewhere between 6% and 8% improvement in cell efficiency relative to what we've had before. So there are a number of steps in the value chain. We not only do our own research but we do a lot of collaboration with universities. So in addition to things with the University of New South Wales, we've just announced a large program at Caltech in the United States to pursue nanotube solar installations, which won't be commercialised tomorrow, but in 2010 to 2020 has a much greater opportunity to come up with yet again, another step improvement in cost and efficiency. Nate Lewis is heading up our Cal Tech program.

Shell and Saint-Gobain form joint venture to develop next generation solar panel production 27/11/2006 The companies announce their joint venture to begin solar power panel manufacturing based on advanced CIS technology.
CIS Thin-Film Technology Advanced CIS (Copper indium diselenide) thin-film technology could provide a real cost breakthrough for solar power. The production process is less complicated, with limited chance of breakage and no usage of expensive silicon. The CIS metal solutions are sprayed onto a glass sheet in layers, comparable with the way coated windows are made, eliminating the need for complex wiring and assembly.
CIS modules are particularly well suited for urban areas. Their smooth black appearance makes them suitable for building integrated applications. Moreover, the technology has excellent performance under low-light conditions e.g. shade.
Shell Solar has played a major role in the development of first-generation CIS technology and has been successfully producing and marketing its products. Shell and Saint-Gobain Glass Deutschland have announced their joint venture, Avancis, to begin solar power panel manufacturing based on advanced CIS technology.
The initial annual capacity of the plant will be 20 MW and is likely to commence in 2008. When built, the plant will manufacture solar panels, which when installed would power an equivalent of around 6,000 European households additional per year with clean energy. Generating the same amount of electricity from a coal-fired power plant would release about 14,000 tonnes of CO2 per year. For more information on Avancis, please visit: http://www.avancis.de/company.html

Thin Film PV
Abstract This paper reviews the state of the art in using electrodeposition to prepare chalcopyrite absorber layers in thin film solar cells. Most of the studies deal with the direct preparation of Cu(In,Ga)Se2 films, and show that the introduction of gallium in the films is now becoming possible from single bath containing all the elements. Electrodeposition can also be used to form precursor films with stacked layer structures, of pure elements or of combinations with binary or even ternary films. Thermal annealing treatments are of dramatic importance to provide suitable electronic quality to the layers. They are often done in the presence of a chalcogen (selenium or sulfur) over pressure and there is a tendency to use rapid thermal processes. Less studies are devoted to complete solar cell formation. Significant progresses have been made in the recent period with several groups achieving cell efficiencies around 8–10% on different substrates. A record efficiency of 11.3% is reported for a cell with an absorber presenting a band gap of 1.47 eV. First results on the manufacturability of the corresponding process to large areas are presented.

Sliver The Best Thing Since Sliced Bread
With an efficiency over 20%, it is the world’s most efficient commercial thin-film solar cell.
News of a sliver technology (read that again, like almonds rather than a noble metal) developed at the Australian National University makes for a nice follow-up to Jim Fraser’s prediction that thin-film solar cells may become the low cost choice for photo voltaic systems in the future.
The cost of producing solar panels could be sliced by more than 60% thanks to technology being developed by Australian researchers, physicists heard today.
Professor Andrew Blakers, director of the Centre for Sustainable Energy Systems at the Australian National University, says ’sliver technology’ could reduce the price of solar power to below the current retail price of electricity. And he says this could make it cost-effective for householders to buy solar panels rather than electricity from the grid.
Blakers describes the latest refinements in the technology at the Australian Institute of Physics conference in Brisbane.
The system works by taking a standard solar cell about 1 millimetre thick and cutting it into tiny slices that are just 120 micrometres wide. “Imagine a standard solar cell is a loaf of bread. When you put it out in the sun it generates energy based on its surface area,” Blakers says. “Now imagine you cut that loaf up into slices and lay them horizontally. You get a lot more surface area.”
This technique allows researchers to use much smaller amounts of expensive silicon to generate the same amount of electricity. This can also keep manufacturing costs down, as all the processing steps normally carried out on solar cells are done while the slices are still in the ‘loaf’.
“We’re looking at major reductions in the total cost without the need for major scientific breakthroughs,” Blakers says. “It’s about doing a good engineering job using known scientific principles, in contrast to some other technologies.”
The sliver technology is also efficient at converting sunlight to electricity, he says. In recent months, the researchers have achieved efficiencies over 20%, making it the world’s most efficient commercial thin-film solar cell.
Now imagine quantum dots in between the slivers. Increasing the surface area also can mean an increase in the thermal load. Quantum dots embedded between layers of a solar cell absorb energy otherwise wasted due to overheating.
