GUWAHATI : Indian Institute of Technology, Guwahati researchers have developed hybrid perovskite-based solar or photovoltaic devices, which are highly efficient, cost effective, easy to manufacture and easily recyclable when it comes to producing electricity from the sunlight.
The emerging perovskite-based semiconducting devices are considered the most promising due to their low-cost, ease of manufacturing as roll-to-roll devices, high material availability and easy recyclability.
These devices were developed achieving power conversion efficiencies beyond 21 per cent by utilizing economical solution-based photovoltaic device processing techniques at mild room temperature and realizing high ambient, thermal and optical stability.
Among all the renewable energy sources, the energy from sun (solar energy) 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, which results in the high price of solar panels. Further, the recycling of solar panels is hazardous and complicated.
“The perovskite solar cells (PSCs) research has experienced tremendous attention due to their exponential growth in terms of efficiencies achieved within a decade. However, the perovskite materials are extremely unstable towards ambient (humidity and oxygen) conditions that restrict their commercialization,” said a release from IIT-Guwahati.
The research team at IIT-Guwahati comprising research scholars Rabindranath Garai (Department of Chemistry), Ritesh Kant Gupta (Centre for Nanotechnology), Arvin Sain Tanwar (Department of Chemistry) and Maimur Hossain (Department of Chemistry), all working under the supervision of Professor Parameswar K. Iyer, Department of Chemistry and Centre for Nanotechnology and School for Health Science and Technology, IIT Guwahati, have achieved the results in terms of efficiency and stability of the PSCs.
In this recent study of IIT-Guwahati, published in the American Chemical Society journal ‘Chemistry of Materials’ mentioned how charged conjugated polymers have been incorporated in photovoltaic devices as a passivation molecule to achieve defect-free high-quality perovskite solar cell devices.Read More…
