“Cadmium Telluride based Thin-Film Solar Cells”

The issue of global warming and the world’s dependence on carbon-emitting fossil fuels is having severe effects on billions of people worldwide due to climate change. To reduce greenhouse gas emissions and decrease dependency on fossil fuels, renewable energies like solar cells are being explored as an alternative energy source. Among these, Cadmium Telluride (CdTe) based solar cells are a popular choice due to their robust materials and high optical absorption coefficient with a suitable band gap for higher photon power conversion. However, the recombination of photo-generated carriers within the solar cell’s interfaces and absorber is a significant challenge to improving device performance. In this talk, the focus will be on minimizing such recombination through materials engineering and controls, with the aim of improving overall device performance.
