Guwahati: The Indian Institute of Technology (IIT) Guwahati researchers have developed hybrid pervksite solar or photovoltaic devices to produce electricity from sunlight.
A perovskite solar cell (PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer.
These devices were developed achieving power conversion efficiencies beyond 21 per cent by utilising economical solution-based photovoltaic device processing techniques at mild room temperature and realising high ambient, thermal and optical stability, researchers said.
As per Parameswar K Iyer, professor at the institute’s department of chemistry and centre for nanotechnology and school for health science and technology said that the PSCs research has experienced remarkable attention due to their exponential growth in terms of efficiencies achieved within a decade.
According to the team, among all the renewable energy sources, the energy from the sun is considered to be the most sustainable due to its ample availability on the surface of the earth.
