solar cell technologies

A photovoltaic cell, which specifically converts sunlight into electrical energy, is one of the most promising technologies towards achieving global renewable energy goals. Crystalline silicon solar cells have become mainstream because of their higher conversion efficiency, yet they are restricted to their massive size and higher cost of production. However, in the last few years, there has been new innovations in this sector giving rise to silicon thin-film materials which is extremely encouraging because of their accessibility, light weight, lower cost, and less demanding manufacture technique. Amorphous silicon (a-Si) is the non-crystalline form of silicon. It is primarily used as semiconductor…
