Flexible solar cell device

Abstract

The invention relates to a flexible solar cell device, which includes a light-transmitting substrate, a light-transmitting panel arranged at a distance from the light-transmitting substrate, a plurality of first solar cell units, a plurality of second solar cell units, and a light-transmitting permanent insulating spacer. The first solar battery unit and the second solar battery unit are alternately interposed between the transparent substrate and the transparent panel along the extending direction of the transparent panel. The first solar cell unit is separated from the adjacent second solar cell unit by the insulating spacer. The thickness of the first solar battery unit and the second solar battery unit is less than or equal to 50 microns. Good flexibility can be ensured, and at the same time, the glass window attached with the solar cell can still maintain good light transmittance.

Description

technical field [0001] The invention relates to a solar cell technology, in particular to a flexible solar cell device. Background technique [0002] The solar cell unit structure mainly includes a light-transmitting substrate, a P-type semiconductor material layer and an N-type semiconductor material layer disposed on the light-transmitting substrate. The solar cell unit mainly applies the principle of photoelectric conversion, which converts the photons of the sun's radiant energy into electrical energy through semiconductor materials. Specifically, when sunlight irradiates a semiconductor, part of the photons are reflected off the surface, and the rest of the photons are absorbed or transmitted by the semiconductor. Part of the absorbed photons becomes heat energy, and the other part of the photons collides with the atomic valence electrons that make up the semiconductor to generate electron-hole pairs. In this way, light energy is converted into electrical energy in th...

Problems solved by technology

However, since organic or polymer compound dyes tend to have short lifespans due to high temperature or sunlight exposure, their materials are easily cracked, and the photoelectric conversion efficiency of these materials is not high.

[0004] In the prior art, the use of semiconductor materials can increase the life of flexible solar cells. However, due to the characteristics or thickness of the semiconductor material absorption spectrum, light cannot be transmitted and the flexibility is poor.
