Abstract

The invention discloses a concentrating photovoltaic power generation assembly which comprises a solar cell, a condensing lens, a secondary condenser, a substrate and a shell. The solar cell is located at the focal point of the condensing lens and a condensing opening of the secondary condenser. The condensing lens, the secondary condenser, the solar cell and the substrate are packaged in the shell in sequence from top to bottom. The solar cell is an efficient triple-junction gallium arsenide solar cell. The condensing lens is a Fresnel lens made of PMMA. The shell is made of hollow glass. In this way, the concentrating photovoltaic power generation assembly is uniform in condensation, high in photoelectric conversion efficiency and low in cost.

Description

Technical field [0001] The invention relates to the field of solar photovoltaic power generation equipment, in particular to a concentrated photovoltaic power generation component. Background technique [0002] Solar energy is an inexhaustible and inexhaustible clean energy. Its use not only solves the depleted fossil energy, but also effectively reduces environmental pollution. Therefore, it is an effective way to develop and utilize new energy and protect the environment. At present, mainstream photovoltaic power generation products at home and abroad are mainly based on monocrystalline silicon, polycrystalline silicon solar cells and amorphous silicon thin-film solar cells. Although the technology development is relatively mature and the system cost is also low, the potential for improvement of photoelectric conversion efficiency is insufficient, and it has not been possible to achieve more Big breakthrough. Therefore, how to improve the conversion efficiency of solar cells w...
