Research Work Title: Perovskite Solar Cells
Abstract: Perovskite solar cells (PSC) are a new paradigm in renewable energy because of their high efficiency reaching over 25%. The perovskite solar cells' high efficiency is due to their excellent optoelectronic properties, which were optimized by various cations and anions with different ratios. Another advantage of perovskite solar cells is their simple fabrication through solution-processing methods, either in n-i-p or p-i-n configurations. However, the PSCs' long-term stability is still a significant concern and is the bottleneck to commercialization. We have developed strategies to enhance the stability by using functionalized ionic liquids as additives and interface engineering by hydrophobic 2-Dimensional perovskite materials, preventing ion migration and protecting the perovskite absorber. The long-term stability of unencapsulated devices under one sun illumination retains>95% of their original efficiencies after 1000 h aging.
