Interfaces in Monolithic Perovskite/ Organic Hybrid Solar Cells: Progresses, Prospects and Challenges

This is the authors' abstract. We don't add key points for this paper.

Combining the merits of the extended light-harvesting spectrum and simple solution-processed fabrication, multi-junction perovskite/ organic hybrid solar cells (POHSCs) undoubtedly show potential for practical energy conversion applications. The POHSCs can be divided into the perovskite/ organic tandem solar cells (POTSCs) and the integrated perovskite/ organic solar cells (IPOSCs), according to whether there is an interconnecting layer (ICL) between the sub-cells. However, the power conversion efficiency (PCE) of POHSCs lags behind other perovskite-based multi-junction devices due to the deficit of light harvesting and the severe carrier loss at the interface. The increased number of interfaces and the stringent requirements on interface properties make it a top priority to obtain efficient POHSCs. In this comprehensive review, we delve into the impact of interfaces on efficiency losses and provide a detailed overview of the latest advancements in interface engineering strategies for POHSCs. Furthermore, we explore the prospects and challenges that lie ahead for the development and optimization of these innovative solar cells.
