Abstract

The invention provides a solar battery structure for group II to V polycrystal semiconductors and a manufacture method thereof. The solar battery structure for the group II to V polycrystal semiconductors comprises a transparent base plate, an amorphous silicon layer and at least one group II to V polycrystal semiconductor layer, wherein the amorphous silicon layer is formed on the transparent base plate by using a plasma assisted chemical vapor deposition method, and the group II to V polycrystal semiconductor layer is sequentially formed on the amorphous silicon layer by a metal organic chemical vapor deposition method. Because the transparent base plate is adopted for replacing the traditional group II to V base plates, the solar battery structure and the manufacture method have the advantages that the cost can be greatly reduced, the area of the solar battery is increased, further, the light absorption area is increased, and the conversion efficiency is improved.

Description

technical field

[0001] The invention relates to a solar cell structure technology, in particular to a solar cell structure of III-V semiconductors and a manufacturing method thereof. Background technique

[0002] Due to the limited resources available on the earth, in order to avoid resource depletion, the solar energy industry has emerged as the times require. Solar energy is a green and sustainable energy source. The development of solar cells can store light energy and make use of it. A solar cell is a semiconductor that absorbs light or photons, and electrons are excited and transition, and the excited electrons drive the circuit to form a battery semiconductor. Various solar cell materials currently used include semiconductor types such as monocrystalline silicon, polycrystalline silicon, and amorphous silicon, or materials linked by elements of groups III, V, and II and VI.

[0003] III-V solar cells, also known as concentrating solar cells, have much higher photoelec...
