What is Perovskite solar cell?

Perovskites are a wide group of materials mainly consisting of hydrogen and carbon. Perovskite photovoltaic cells are more lightweight and affordable compared to conventional PV cells made from silicon. Though silicon-based solar modules are the most widespread solar products for the time being, they are too pricey. Silicon panels are so expensive because pure silicon is a rare material. Converting silicon into the form suitable for use is a high-priced and energy-consuming process. Silicon PV modules are huge and weighty. Moreover, the conversion efficiency of silicon solar products is only around 25 percent, which lower than that of perovskite ones. All the above factors have made perovskite photovoltaic devices commercially competitive with silicon PV panels.
