Problems solved by technology

When concentrating solar cells are used for electrical energy conversion, due to the limitation of the spectral absorption capacity of the energy band gap of the material itself, it is impossible to convert 100% of the light energy into electrical energy output, so the excess energy entering the solar cell Infrared light (>1100nm) is easy to form heat energy accumulation 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 condensing type soler battery module with lower calorific value. The soler battery module with lower calorific value comprises a solar battery chip, a circuit supporting plate, a collecting lens and an infrared isolation element. The product provided by the invention can effectively reduce heat source generated by infrared irradiation, in order to eleminate the problem that the condensing type soler battery module has an excessive temperature; moreover, the infrared isolation elemt has has a simple processing method, thereby effectivly reducing production cost.

Description

technical field [0001] The invention relates to a solar cell module, in particular to a low calorific value concentrating solar cell module. Background technique [0002] As a converter of new energy sources, solar energy has the advantages of simple structure, no regeneration pollution, etc., and is a clean energy source, so it has been widely developed and utilized. Among them, concentrating photovoltaic (CPV) mainly uses lenses to gather sunlight in a narrow area to improve power generation efficiency. However, under the condition of high-magnification concentrating light, the temperature of the solar cell module will rise rapidly as the concentrating magnification increases, which will lead to a large increase in the dark current inside the battery and reduce the conversion efficiency of the battery. [0003] Referring to US Patent No. 7851693 "Passively cooled solar concentrating photovoltaic device", the concentrating solar device 100 disclosed in this patent is as fo...
