GUWAHATI: Researchers at the Indian Institute of Technology (IIT) Guwahati have developed hybrid perovskite-based solar or photovoltaic devices to produce electricity from sunlight, which are highly efficient, cost effective, easy to manufacture and easily recyclable.
These devices are developed to achieve power conversion efficiencies beyond 21% by utilising economical solution-based photovoltaic device processing techniques at mild room temperature and realising high ambient, thermal and optical stability.
Among all the renewable energy sources, the energy from the sun (solar energy) is considered to be the most sustainable due to its ample availability on the surface of the earth. Currently, inorganic solar cells (Silicon-based) are 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.
The research team at IIT Guwahati comprising of research scholars Rabindranath Garai (Department of Chemistry), Ritesh Kant Gupta (Centre for Nanotechnology), Arvin SainTanwar (Department of Chemistry), Maimur Hossain (Department of Chemistry) working under the supervision of Prof Parameswar K Iyer, Department of Chemistry and Centre for Nanotechnology and School for Health Science and Technology, have achieved remarkable results in terms of efficiency and stability of the Perovskite Solar Cells (PSCs).
