Roorkee (The Hawk): Indian Institute of Technology Roorkee (IIT Roorkee) researchers led by Prof. Soumitra Satapathi from the Department of Physics have successfully developed high-quality perovskite solar cells. The prototype has shown a stabilised power conversion efficiency of 17.05%, which is one of the highest reported PCEs for quasi-two-dimensional (2D) perovskite. The modified perovskite solar cell leads to the optimum phase distribution, enlarged grain size, and improved crystallinity. This finding offers new opportunities and the development of highly efficient perovskite solar cells with long-term operational stability. Among all the renewable energy sources, the sun's energy is considered the most sustainable due to its ample availability on the earth’s surface. And just over a decade ago, perovskite solar cells established themselves as the next generation of photovoltaic technology due to their comparably higher PCE and cheaper and simpler manufacturing processes than silicon solar cells. Several methods and processes have been developed based on the potential to produce high-quality perovskite solar cells. The quasi-2D layered perovskites have gained significant attention recently for their exceptional optoelectronic properties, structural diversity, and excellent ambient stability. These additives can effectively control the perovskite growth kinetics and exhibit an efficient role as passivating agents for defect annihilation. This has motivated Prof. Satapathi and his team, including Ms. Yukta, Research Scholar, IIT Roorkee, to take up this research to develop low-cost and highly efficient perovskite solar cells. The research article for the finding has been published in journal ACS Applied Energy Materials  Talkin ...
