Solar cell component

Abstract

The invention relates to a solar cell assembly, which comprises a flexible solar cell, wherein the flexible solar cell comprises a first surface for receiving solar radiation energy, and a second surface which is corresponding to the first surface. A shape memory body alloy layer is attached on the second surface, in order to make the flexible solar cell change shapes as the shape changes of the shape memory body alloy layer.

Description

technical field [0001] The invention relates to a solar cell assembly, in particular to a solar cell assembly capable of changing shapes. Background technique [0002] The solar cell mainly applies the principle of photoelectric conversion, and its structure mainly includes a substrate and a P-type semiconductor material layer and an N-type semiconductor material layer arranged on the substrate. [0003] Photoelectric conversion refers to the process in which photons of solar radiation energy are converted into electrical energy through semiconductor materials (see "Grownjunction GaAs solar cell", Shen, C.C.; Pearson, G.L.; Proceedings of the IEEE, Volume 64, Issue 3, March 1976Page(s ): 384-385). When sunlight shines on a semiconductor, part of it is reflected off the surface, and the rest is absorbed or transmitted by the semiconductor. Some of the absorbed light turns into heat energy, and some photons collide with the atomic valence electrons that make up the semicondu...

[0005] However, the substrates of general solar cells are made of materials such as monocrystalline silicon, polycrystalline silicon or glass. Most of the solar cells based on these materials can only receive the sun's radiation in a fixed direction, which will have a large part of the radiation energy. Wasted because it cannot be received by the solar cell
