Title:

DOUBLE-SIDED COUPLING PHOTOVOLTAIC CELL SYSTEM BASED ON REFLECTION AND CONDENSATION

Document Type and Number:

WIPO Patent Application WO/2020/258989

Kind Code:

A1

Abstract:

Disclosed in the present invention is a double-sided coupling photovoltaic cell system based on reflection and condensation, which is composed of one or more structural units. Each structural unit consists of a double-sided photovoltaic cell and two reflection-type photovoltaic cells; the two reflection-type photovoltaic cells are respectively positioned on two sides of the double-sided photovoltaic cell; light receiving surfaces of the reflection-type photovoltaic cells face the double-sided photovoltaic cell; an included angle is formed between each reflection-type photovoltaic cell and the double-sided photovoltaic cell, so that incident light can irradiate the two surfaces of the double-sided photovoltaic cell after being reflected by the reflection-type photovoltaic cells. The present invention solves the problem of performance attenuation of a narrow band gap cell caused by reduced carrier concentration in a conventional multi-band gap photovoltaic cell combination, can more effectively utilize sunlight of different wave bands, fully exerts the performance of a multi-band gap photovoltaic cell system, and improves the photoelectric conversion efficiency. The battery system is simple in structure and easy to achieve.
