Abstract

The invention discloses a perovskite monocrystal material and microcrystalline silicon composite material combined thin film solar cell, and relates to a semiconductor device specially applied to converting an optical energy into an electric energy. The perovskite monocrystal material and microcrystalline silicon composite material combined thin film solar cell comprises a bottom electrode, an N type oxide semiconductor film, a perovskite monocrystal light absorption layer, a microcrystalline silicon hole transporting layer and a top electrode; the oxide semiconductor thin film is an N type zinc oxide semiconductor thin film obtained by sputtering; the perovskite monocrystal light absorption layer is a light absorption material of a perovskite structure; the hole transporting layer is a P type microcrystalline silicon composite material obtained by chemical vapor deposition; and the bottom and top electrodes are films made of aluminum or silver and obtained by thermal evaporation. According to the perovskite monocrystal material and microcrystalline silicon composite material combined thin film solar cell and a preparation method thereof, the perovskite monocrystal is taken as the light absorption material and the P type microcrystalline composite material is taken as the hole transporting layer, so the more stable and more efficient solar cell is obtained.

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 compounded with perovskite single crystal material and microcrystalline silicon and a preparation method thereof. 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. [0003] One type of solar cell is a microcrystalline silicon thin film solar cell. This kind of battery is to de...
