Although single-crystal solar cells have achieved a PCE exceeding 23%, there is still a notable disparity between their performance and the theoretically predicted efficiency of over 30%. To enhance PCE, it is essential to reduce the thickness of SCTFs to alleviate intrinsic resistance and bolster charge carrier extraction.
Therefore, single-crystal perovskite solar cells (SC-PSCs) have recently received significant attention in the fabrication of highly efficient and stable PSCs owing to their synergistic properties. The development of advanced SC-PSCs represents a promising pathway to fabricate highly efficient and stable perovskite-based solar cells.
From the Si ingots grown to the wafers which can be used to fabricate solar cells, excessive machining is required. The breaking of Si wafer and cracking of Si ingot directly lead to the waste of material cost. So, the diamond line slicing process determines the production cost of the entire Si solar cell industry.
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 current thickness of SCTFs, approximately 10 μm, remains too large for vertical structure devices. Although single-crystal solar cells have achieved a PCE exceeding 23%, there is still a notable disparity between their performance and the theoretically predicted efficiency of over 30%.
Conventional solar cells consist of crystalline semiconductors based on Si, Ge, and GaAs. Such solar cells possess higher efficiency and stability than polycrystalline solar cells, and SC-PSCs are inferior to PC-PSCs in terms of efficiency.
