Abstract

A tin sulfide thin film solar cell comprises a conductive glass / metal gate electrode and a metal back electrode and is characterized in that uni-junction or multi-junction n-SnS2 or the composite thin film thereof and p-SnS or the composite thin film thereof are formed between the conductive glass / metal gate electrode and the metal back contact. The composite means the tin sulfide obtained by doping tin bromide (n-SnS2) and stannous sulfide (p-SnS). The solar cell is rich in material sources, safe and environment-friendly, convenient in processing and effectively solves the collection problem of current carriers with the aid of such electrodes as metallic tin by using SnS2 and SnS, which have the same components and different conduction types and liable to realize energy gap match, heterojunction transition and good transport property of the current carriers.

Description

1. Technical field [0001] The invention relates to a compound thin film solar cell, specifically a tin sulfide thin film solar cell. 2. Background technology [0002] Energy crisis and environmental pollution are major challenges facing human beings. Fully developing and utilizing solar energy has become a strategic decision for sustainable energy development of governments around the world. The development of cost-effective solar photovoltaic cells and their utilization technologies is a priority direction for the low-cost and large-scale development and utilization of renewable energy. Research on solar cell-related materials and their key technologies is an important part of high-efficiency energy materials technology. Therefore, the research and use of solar cells to directly convert solar energy into electrical energy and realize photovoltaic grid-connected power generation will change the traditional energy structure, alleviate human energy shortages in the future, and...
