Abstract Perovskite solar cells (PSCs) have attracted widespread research and commercialization attention because of their high power conversion efficiency (PCE) low fabrication cost. The long‐term stability PSCs should satisfy industrial requirements for photovoltaic devices. Inverted with a p‐i‐n architecture exhibit considerable advantages excellent competitive efficiency. continuously broken‐through PCE inverted shows huge application potential. This review summarizes the developments outlines characteristics including charge transport layers (CTLs), perovskite compositions, interfacial regulation strategies. latest effective CTLs, modification, promotion strategies especially under light, thermal, bias conditions are emphatically analyzed. Furthermore, applications structure in high‐efficiency stable tandem, flexible devices, modules main obstacles systematically introduced. Finally, remaining challenges faced by devices discussed, several directions advancing proposed according to development status industrialization requirements.

Metal halide perovskite single crystals are promising for diverse optoelectronic applications. As a universal issue of solution-grown crystals, surface contamination causes adverse effect on material properties and device performance. Herein, learning from the self-cleaning lotus leaf, we address by introducing an amphiphilic long-chain organic amine into crystal growth solution. Self-assembly CTAC provides hydrophobic surface, inducing spontaneous removal residual solution, which results in clean better crystals. An impressive efficiency 23.4 % is obtained, setting new record FA

Grain-free single-crystal perovskites offer a potential avenue to the stability of advance perovskite solar cells (PSCs) beyond that polycrystalline films. Recent progress in PSCs (SC-PSCs) has come primarily from methylammonium (MA)-containing (e.g., FA0.6MA0.4PbI3) devices, which have achieved 23.1% power conversion efficiency (PCE). Yet, such are intrinsically vulnerable thermal stresses, given relative volatility MA molecule within structure. Herein, we demonstrate MA-free SC-PSCs based on an ∼20-μm-thick Cs0.05FA0.95PbI3 absorber layer, achieves new and benchmarks for SC-PSCs. Our devices exhibit 24.29% PCE retain 90% their initial after 900 h at 53 °C. Accelerated aging tests single crystals show they endured damp heat test (85 °C/65% RH) approximately twice as long films same composition. These results indicate FAPbI3-based SCs promising candidates develop road commercialization.
