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.

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.
The details for the simulation of crystal thickness-dependent efficiency limit of the single crystal solar cells can be found in the Supplementary Note. Though increased J SC slightly increases V OC, larger thickness of perovskite films increases the charge recombination during their transport and thus J 0, which reduces V OC.
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.
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.
