Abstract

The invention discloses a concentrating photovoltaic power generation device which comprises a condenser lens, a light barrier, a secondary optical element, a concentrator solar cell, a radiator and a shell, wherein the condenser lens is spliced at the upper end of the shell by sealing glue; the light barrier is positioned under the condenser lens and connected with a box body into a whole; the light barrier is evenly provided with light holes, a uniform light optical element is positioned just under the light holes, the secondary optical element is spliced on the surface of the concentrator solar cell by light guide glue, the concentrator solar cell is spliced on the radiator by heat conduction glue, and the radiator is fixed on a bottom plate of the shell. Compared with the prior art, the concentrating photovoltaic power generation device has the characteristics of high condensation multiplying power and conversion efficiency, rapid heat dissipation, small land occupying area and effectively reduced cost.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to a concentrated photovoltaic power generation device. It is a power generation device that can enhance the power generation output of solar photovoltaic cells and reduce the usage of solar photovoltaic cells. Background technique [0002] Traditional flat solar panels have low conversion efficiency and occupy a large area. At present, the reflective concentrated photovoltaic power generation device should be the first to promote the light funnel. Its theoretical limit concentration ratio is 7 times, and the actual application is 3 to 4 times. It is difficult to greatly improve the power generation efficiency, and the relative price is relatively expensive, which hinders solar energy Promotion and application of power generation. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the above-mentioned exis...
