Described a kind of concentrator cell assembly; It is characterized in that the assembly light concentrating times selects as required on caustic surface, when using, adopt flat single tracing to use, when using, adopt accurate two-dimensional tracking as high power concentrator as the low-concentration assembly; Assembly can be that small-sized monomer or small-sized set of monomers are fit; Also can be major comonomer or major comonomer assembly, can also be combined into a superelevation times optically focused ultra-large type monomer, assembly adopts sealing or unlimited mode.

Described a kind of concentrator cell assembly; It is characterized in that no matter being low power or high power or superelevation times concentrator cell assembly; All must solve corresponding heat dissipation problem, adopt the heat radiation of air wind-cooling heat dissipating or recirculated cooling water, the silion cell maximum temperature is not higher than 70 ℃; CIGS battery or multi-junction gallium arsenide battery maximum temperature are not higher than 170 ℃; Have ready conditions and adopt the water-cooled effect best, high-temperature steam during high power concentrator multi-junction gallium arsenide battery water-cooled can obtain simultaneously is for solar airconditioning, bring high-quality and efficient exchange thermal source.

Adopt such scheme, the present invention mainly contains following innovative point.

(1) cuts apart the concentrator that is combined into by linear Fresnel lens among the present invention; Have arbitrarily adjustable characteristic of high low power light concentrating times, and the focal spot shapes rule, be fit to very much various battery components and use; Simplified the concentrator structure; Be the assembly of a kind of point focusing and line focus, possessed the optically focused characteristic of inverted pyramid shape light funnel, have a extensive future.

(2) battery component among the present invention; When adopting the multi-junction gallium arsenide battery, can use superelevation times concentrator cell use more than 1000 times, few battery consumption and 40% generating efficiency; Bring low-cost generating, for a ultra-large type superelevation times concentrating to generate power brings the great competition advantage.

(3) high-temperature steam during concentrator cell assembly among the present invention, high power concentrator can obtain when adopting water-cooling for solar airconditioning, warmer, drier, swimming pool etc. bring high-quality and efficient exchange thermal source, has improved the solar energy utilization ratio greatly.
