Problems solved by technology

When concentrating solar cells are used for electrical energy conversion, due to the limitation of the energy bandgap of the material itself on the spectral absorption capacity, it is impossible to convert 100% of the light energy into electrical energy output, so the excess infrared energy entering the solar cell Light (>1100nm) is easy to form heat energy and accumulate in the battery, causing the temperature of the components to rise, resulting in a large increase in the dark current inside the battery and reducing the conversion efficiency of the battery

Abstract

The invention relates to a reflection type condensed light type solar battery module, and the solar battery module contains a reflection type collecting lens, an infrared isolation element and a solar battery chip. The product provided by the invention can effectively reduce heat energy generated by infrared light wave length energy and eleminate the problem that the condensed light type solar battery module has a very high temperature.

Description

Technical field [0001] The invention relates to a solar cell module, in particular to a reflective type concentrating solar cell module. Background technique [0002] As a converter of new energy sources, solar energy has the advantages of simple structure and no regeneration pollution. It is a kind of clean energy, so it is widely developed and utilized. Among them, the concentrating photovoltaic (CPV) mainly uses lenses to concentrate sunlight on a small area to improve power generation efficiency. However, under high-power concentrating conditions, the temperature of the solar cell module will rise rapidly with the higher the concentrating power, leading to a large increase in the dark current inside the battery and reducing the battery conversion efficiency. [0003] With reference to US Patent No. 7851693 "Passively cooled solar concentrating photovoltaic device", the concentrating solar device 100 disclosed in this patent is such as figure 1 As shown, it includes an optical ...
