Abstract

The invention provides an indoor wide-spectrum wide-visual-angle condensation photovoltaic solar cell testing device which has the main function of testing III-V family condensation solar cells under different condensation multiples. The indoor wide-spectrum wide-visual-angle condensation photovoltaic solar cell testing device comprises an optical table, a simulated light source, a cell fixture and a testing system, wherein the simulated light source positioned on the optical table emits light rays; and the testing system measures the photovoltaic characteristic curve of the solar cell to be measured. The invention is characterized by also comprising a condensation system, wherein the condensation system comprises a condensation lens, a field lens and a collimating mirror which are sequentially arranged in an optical path; and the condensation system is used for condensing the light rays onto the solar cell to be measured. The invention has the advantages of stable simulated sunlight, adjustable light source intensity, wide spectrum, wide visual angle and many condensation multiples.

Description

technical field [0001] The invention relates to the field of solar cell testing. Background technique [0002] Today, as fossil resources are increasingly scarce, solar photovoltaic applications, as a clean and non-polluting energy output method, have very good application prospects. However, due to the limitation of high solar cell production costs, the promotion of photovoltaic applications has been affected. Because the cost of photovoltaic applications is mainly concentrated on photovoltaic cells, the use of concentrated photovoltaic technology can generate greater energy output on smaller solar cells than ordinary solar cells of the same area. [0003] Concentrating photovoltaics directly convert sunlight into electricity through high conversion efficiency photovoltaic cells after concentration, so that part of the cost is transferred from the photovoltaic cells themselves to the focusing system and solar tracking system, which is an effective way to reduce the system c...
