The as-grown perovskite single-crystal films can be directly printed on various substrates, and the film thickness can be flexibly tailored in a wide range by the seed size. The perovskite single-crystal films show high crystalline quality compared with the best quality of bulk perovskite single crystals reported to date.
Synthesis control over the orientation and thickness of large-area single-crystal films is required to put this technology a step ahead regarding their integration into the aforesaid photovoltaic devices.
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.
Challenges and possible solutions Research on the photovoltaic applications of single-crystal perovskite is in its early stages, where the gradual but continuous development of single-crystal-based PSCs have led to the utility of single-crystal perovskites for fabricating highly stable and efficient PSCs.
However, there are almost no grain boundaries in single crystals, which indicates the traps are primarily distributed on the surface and bulk. As a result, there are fewer trap densities (≈10 10 cm −3) compared with thin films (≈10 14 cm −3 to 10 17 cm −3) .
The growth of high-quality single-crystal (SC) perovskite films is a great strategy for the fabrication of defect-free perovskite solar cells (PSCs) with photovoltaic parameters close to the theoretical limit, which resulted in high efficiency and superior stability of the device.
