IIT Guwahati Announces Perovskite Solar Cell Reaching 25.73% Efficiency

Researchers at the Indian Institute of Technology Guwahati have unveiled a new perovskite solar‑cell design. The prototype achieved a conversion efficiency of 25.73 percent under laboratory conditions. This efficiency rivals that of many commercial silicon‑based panels. The breakthrough demonstrates the rapid progress of perovskite materials for photovoltaics. Higher efficiency could lower the cost per watt of solar electricity. The team plans further testing to improve stability and scalability. The development was reported by Saur Energy. Industry observers will watch for potential commercialization pathways.
