Total spectrum solar concentrator

illustration.

A total spectrum solar concentrator is a device used to optimise the efficiency of solar power. The suns rays are first concentrated using parabolic mirrors or a fresnel lens, and then spread out into a light spectrum via a prism. Each different part of the spectrum is aimed at a solar cell manufactured to operate most efficiently in that wavelength range.

This technology has multiple problems, most notably in that it results in only marginal gains in efficiency^{[citation needed]}.
