Abstract:

Lightweight and physically flexible features, which can be shaped into complex forms. The small material requirements and the increased performance of the thin film solar cells make them desirable. Cd-Se-Te and Cd-S-Te alloy may be studied to progress optoelectronic materials that have better light absorption and variable bandgaps. Photovoltaic, photodetectors and light emitting devices require these alloys. Selenium doping causes the bandgap to become narrower, and sulfur provides a greater amount of energy photons. They are synthesized efficiently and exhibit improved charge carrier dynamics, allowing increased efficiency and increased lifetime in renewable energy technologies and semiconductor technologies. This paper has analyzed and categorized the evolution of solar cell material. Also, thin film Cd-Te solar cells and doping of these cells with different elements are introduced
