Single crystal based solar cells as the big new wave in perovskite photovoltaic technology. Potential growth methods for the SC perovskite discussed thoroughly. Surface trap management via various techniques is broadly reviewed. Challenges and potential strategies are discussed to achieve stable and efficient SC-PSCs.
Because of several issues related to the polycrystalline form of perovskites, researchers are now focusing on single-crystal perovskite solar cells (SC-PSCs). Conventional solar cells consist of crystalline semiconductors based on Si, Ge, and GaAs.
To achieve this aim, we follow a top-down approach, i.e. treating ready-made perovskite single crystals in a way so that they can be used in typical solution-processed perovskite solar cell architectures.
However, research on single-crystal perovskites remains limited, leaving a crucial gap in optimizing solar energy conversion.
In just over a decade, the power conversion efficiency of metal-halide perovskite solar cells has increased from 3.9% to 25.5%, suggesting this technology might be ready for large-scale exploitation in industrial applications. Photovoltaic devices based on perovskite single crystals are emerging as a viable alternative to polycrystalline materials.
Although power conversion efficiencies have generally been lower than in polycrystalline thin film devices, single crystal perovskite solar cells not only offer potentially improved long-term stability 23, 24, 25 but also can achieve as much as 17.8% efficiency in a single crystal film grown in situ on a half-built solar cell stack 26.
