IIT Guwahati Team Develops Efficient Perovskite Solar Cells To Produce Electricity From Sunlight

Researchers at the Indian Institute of Technology (IIT) Guwahati have developed hybrid pervksite solar or photovoltaic devices to produce electricity from sunlight, which are highly efficient, cost effective, easy to manufacture and easily recyclable, according to officials. 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, they said.

A Perovskite Solar Cell (PSC) is a type of solar cell which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer.

Parameswar K Iyer, Professor at the institute’s Department of Chemistry and Centre for Nanotechnology and School for Health Science and Technology, under whose supervision the research was conducted explained that the PSCs research has experienced tremendous 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. Currently, inorganic solar cell (Silicon-based) is a major player in the market. However, this technology requires high-temperature processing that results in the high price of solar panels. Further, the recycling of solar panels is hazardous and complicated.
