Antimony Selenide, A New Research Achievement of Thin Film Solar Cell

Features for Thin Film Solar Cells

The energy crisis has led to a rise in energy problems such as the loss of oil, natural gas and coal. This combined with the fact that the quality of the environment is declining makes it difficult for countries to develop new energy solutions. Low production costs, excellent low light and high temperatures power generation performance as well as light weight and flexibility make thin-film solar cell competitive with silicon-based cells. They also have advantages in other areas such photovoltaic build integration and mobile power supply.

Benefits of Antimony Selenide Tin Film Solar Cells

Cadmium Telluride cells (CdTe), which are currently the most well-known thin film solar cells available, is highly toxic. Cadmium is also scarce. Professor Tang has directed his research efforts to develop a novel type of antimony-selenide (Sb2Se3) thin-film solar cell. This is despite the fact that cadmium (CdTe), which can cause severe skin reactions, has replaced the Rapid Thermal Evaporation method (RTE). The Vapor Transport deposition (VTD), has the added step of making antimony selenide thin sheets. Common quartz tube furnace is used for this process. This method is more cost-effective than RTE and has a simpler equipment design.

Optimizement Results for Antimony Selenide Thin Film Solar Cell

Following systematic optimization in the process for antimony selenide thick film preparation, the research team obtained an antimony selenide solar cell with a certified photoelectric efficiency of 7.6%. The current world record is 7.6% for solar cell efficiency using antimony selenide.
