A photovoltaic keyboard is a wireless computer keyboard that charges its batteries from a light source such as the sun or interior lighting, addressing a major drawback of wireless computer peripherals that otherwise require regular replacement of discharged batteries.
The Logitech K750 has a set of photovoltaic cells on the top edge, charges in sunlight or under a standard bulb, can work up to three months in total darkness, and includes software to display battery charging status. It is a numerical keyboard - meaning it includes the NumPad section on the right side. It is compatible with Windows or Macintosh operating systems.
Even though the keyboard is not officially supported in Linux, a third party application named Solaar provides functionality akin to the original Logitech software, such as battery and connection status indications, and allows device pairing/unpairing.
