The growing energy scarcity and the need to combat climate change necessitate the development of renewable and low-cost clean energy technologies. Photovoltaic conversion technology, which uses the sun's energy to generate electricity, is an attractive solution. Currently, silicon solar cells dominate the market, but innovative alternatives are needed. Perovskite solar cells (PSCs) have the greatest potential due to their efficiency, optoelectronic properties, and low cost. However, interface loss mechanisms, intrinsic instability, and control of interface heterostructures pose significant challenges to their large-scale applications and commercialization. One of the most important issues in photovoltaics is developing resilient and environmentally benign perovskite materials with superior stability while preserving photovoltaic performance. Interface defect passivation is critical for enhancing the performance of perovskite solar cells. Functional molecules are applied at the interface to enhance charge transport, but the detailed mechanism underlying this process requires further understanding. A novel category of perovskites, 2D perovskites, has emerged, boosting thermal and moisture stability. Post-treatment of the 2D perovskite on the 3D perovskite improves interface properties and heightened stability. The inclusion of an organic spacer cation with diverse functional groups and varying chain lengths could offer the desired properties for highly stable and efficient PSCs. The goal is to employ cutting-edge experimental and spectroscopic techniques to pinpoint tailored interfaces with 2D-3D engineering to develop them into efficient thin-film PVs processed at low temperatures using scalable methods.
