Specific embodiment
The central scope of the utility model is, in order to improve efficiency, inventor is in existing photoelectric conversion material, choosing
The GaAs usually used on satellite is selected, since the forbidden band of GaAs is width compared with silicon, so that its spectral response and sky
Between solar spectrum matching capacity it is good compared with silicon, the theoretical efficiency of silion cell is about 23%, and the gallium arsenide cells theory of unijunction is imitated
Rate reaches 27%, and the gallium arsenide cells theoretical efficiency more tied is more more than 50%, and temperature tolerance is good, conventionally, GaAs electricity
The temperature tolerance in pond is better than silicon photocell, has experimental data to show that gallium arsenide cells still can normal work under conditions of 250 DEG C
Make, but silicon photocell has just been unable to operate normally at 200 DEG C.The shortcomings that material, is, at high price, therefore in order to drop
Low cost, inventor have selected optically focused solar structure, while in order to avoid using complicated sun tracing system, and reduction system
The size of system, inventor analyze sunshine rule, it is contemplated that the elevation angle variation of sunshine is little among one day, and angle is with the sun
The sunset that rises to do not changing all the time, therefore, concentration structure is designed as to the bar shaped convex lens of horizontal-extending strip
Mirror keeps light convergence into a line, is incident upon on the GaAs photovoltaic chip arranged into strips.
As shown in Figures 1 and 2, a kind of solar energy high power concentrating photovoltaic device of the utility model mainly includes adjustable folder
