Description

technical field [0001] The technical solution of the invention relates to a semiconductor device specially suitable for converting light energy into electric energy, specifically a thin-film solar cell combined with perovskite single crystal material and P-type single crystal silicon and its preparation method. Background technique [0002] The use of solar energy is a major breakthrough in the progress of human society. With the decline of fossil fuels, solar energy has become an important part of energy used by human beings and has been continuously developed. As a renewable energy source, solar energy is mainly used to convert solar energy into electrical energy, which is then applied to all aspects of human life. Low-cost, high-efficiency and long-term stable solar cells are the basis for realizing large-scale photoelectric conversion using solar energy.

AI Technical Summary

Problems solved by technology

There are many grains, grain boundaries, pores and surface defects in the mixed phase film of amorphous and microcrystalline, which will cause the recombination of carriers, and the perovskite in the film state has high sensitivity to temperature, humidity and gas. Responsive, easily affected, loses its original properties

Therefore, the current solar cells combined with perovskite and silicon have the disadvantages of low photoelectric conversion performance and insufficient stability.
