Abstract

The present invention aims to provide a concentrator photovoltaic conversion device having the advantages of no need for redesigning a band gap, using existing solar cells obtained from non-solar cell manufacturers, easy manufacturing, easy thermal design, and capacity of suppressing reduction of conversion efficiency even in the case of improved concentrating efficiency. In order to solve the problems, the present invention provides the concentrator photovoltaic conversion device, comprising a concentrating mirror and a photovoltaic conversion element arranged opposite to the concentrating mirror, wherein the photovoltaic conversion element comprises a light scattering-used solar cell having a through hole, and a concentrating-used solar cell arranged in the through hole of the light scattering-used solar cell, in addition, the concentrating mirror is formed by transparent thermosetting resin, and the photovoltaic conversion element is carried on an external connection substrate.

Description

Technical field [0001] The invention relates to a concentrating type photoelectric conversion device and a manufacturing method thereof. Background technique [0002] In the past, as a photoelectric conversion device, a solar power generation device that converts solar energy into electrical energy has been put into practical use. In order to achieve low cost and further obtain more power generation, a concentrating photoelectric conversion device has been put into practical use. The condenser lens irradiates the collected sunlight to the solar cell element smaller than the light-receiving area of ​​the condenser lens to obtain electric energy (for example, refer to Patent Document 1). [0003] However, the prior concentrating photoelectric conversion device has the following problem: On a sunny day, compared with flat panel solar modules (modules) using ordinary silicon solar cells, more power can be obtained, but it is almost impossible to obtain power on a cloudy day. the amoun...
