Indian scientists have developed perovskite mini-modules with reduced graphene oxide interface engineering, achieving 16.6% efficiency and over 1,300 hours of stable operation. A study published in Solar Energy Materials and Solar Cells demonstrated that a new cell and module concept using r-GO interfacial passivation and optimized transport layers achieved over 95% efficiency after 1,300 hours of operation and storage. The graphene oxide layer improves film quality, reduces defects, enhances charge transport, and enables scalable fabrication, offering a promising route toward efficient and durable perovskite solar modules. The academics involved in the study believe this approach is effective for creating more efficient and durable perovskite modules, providing a promising pathway for bridging the gap between laboratory-scale devices and commercially viable perovskite solar modules.
