In the evolving field of photovoltaics, hybrid and organic solar cells, particularly organic-inorganic hybrid perovskite solar cells (PSCs), have shown remarkable progress in achieving power conversion efficiencies close to traditional silicon-based systems. Despite this, the long-term stability of PSCs remains a significant hurdle, limiting their commercial potential. This presentation will focus on the innovative use of interface engineering to enhance the durability and performance stability of PSCs. By examining the root causes of instability and the latest strategies for interface manipulation, we aim to illuminate how these techniques not only mitigate surface defects but also protect the perovskite core from environmental degradation. We have explored a variety of interface modification agents and their roles in stabilizing the perovskite structure, including the application of low-dimensional perovskite capping layers and the design of advanced charge transport layers. The presentation will delve into the fundamental insights and mechanisms behind device degradation, presenting cutting-edge methods to counteract these challenges. Additionally, we will discuss the broader implications of these developments for the future of hybrid and organic photovoltaics, emphasizing the critical role of interface engineering in paving the way towards more reliable and efficient solar technologies.
