And described hollow tetragonous cone table and tetragonous cone table lens are positive tetragonous cone table.
Advantage of the present utility model and good effect are:
The utility model is simple in structure, be convenient to processing and later stage assembling, hollow tetragonous cone table reflection device and tetragonous cone table lens are combined, be connected with solar cell by firm banking, the light of lens focus is converged by hollow tetragonous cone table reflection device and tetragonous cone table lens once more.This structure improved light sink-efficiency, improve the equal property converge spectrum, the tolerance that increases angle, thereby improve the generating efficiency of whole system, with the accepting the angle and increase to of sun tracking system+/-0.5 °, make photoelectric conversion efficiency improve 1%.
