Abstract

The invention discloses an antimony-base compound thin film solar cell and a manufacturing method of the antimony-base compound thin film solar cell and belongs to the manufacturing field of photoelectric material and thin film solar cells. The problems that in an existing compound thin film solar cell, needed material is little in the earth crust, high in price and toxic to the human body or complex in production technology are solved. The antimony-base compound thin film solar cell comprises a substrate, a back electrode layer, a P-type absorption layer, an N-type buffering layer, an oxide thin film window layer and metal gate electrodes in a sequential deposition mode. The P-type absorption layer is made of CuXSbybetaZ material, wherein beta is S or Se. The material of the P-type absorption layer is selected from high-abundance elements in the earth crust, wherein the material is rich in resource and environmentally friendly because no toxic components are contained, the range of the energy gap of the elements is about 0.5 ev-2.5 ev, the spectral response range is wide, the light absorption coefficient is up to 105 cm-1, and therefore the compound thin film solar battery composed of the material has excellent photovoltaic performance and is environmentally friendly, and low-cost production is expected to be achieved.

Description

technical field [0001] The invention belongs to the field of photoelectric materials and thin-film solar cell preparation, and in particular relates to an antimony-based compound thin-film solar cell and a preparation method thereof. Background technique [0002] With the development of the economy, the demand for energy has increased sharply, the depletion of non-renewable energy and the environmental pollution caused by the combustion of fossil fuels have become more prominent. Solar cells, as a clean and pollution-free new energy source, have received a lot of attention. A solar cell is a device that uses the photovoltaic effect to directly convert solar energy into electrical energy. Multi-component compound thin-film solar cells have received more attention due to their advantages such as less material consumption, low energy consumption for preparation, good low-light and high-temperature performance, light weight, flexible cells, and wide application range. The exist...
