Incorporating mixed ion is a frequently used strategy to stabilize black-phase formamidinum lead iodide perovskite for high-efficiency solar cells. However, these devices commonly suffer from photoinduced phase segregation and humidity instability. Herein, we find that the underlying reason halide perovskites generally fail grow into homogenous high-crystalline film, due multiple pathways of crystal nucleation originating various intermediate phases in film-forming process. Therefore, design...
Abstract Recently, organic–inorganic metal halide perovskite solar cells (PSCs) have achieved rapid improvement, however, the efficiencies are still behind Shockley–Queisser theory mainly due to their high energy loss ( E LOSS ) in open‐circuit voltage V OC ). Due polycrystalline nature of solution‐prepared films, defects at grain boundaries as non‐radiative recombination centers greatly affect and limit device efficiency. Herein, poly(vinylidene fluoride) (PVDF) is introduced...
Abstract Interfacial engineering of perovskite films has been the main strategies in improving efficiency and stability solar cells (PSCs). In this study, three new donor‐acceptor (D–A)‐type interfacial dipole (DAID) molecules with hole‐transporting different anchoring units are designed employed PSCs. The formation interface dipoles by DAID on film can efficiently modulate energy level alignment, improve charge extraction, reduce non‐radiative recombination. Among molecules, TPA‐BAM amide...
Although the power conversion efficiency values of perovskite solar cells continue to be refreshed, it is still far from theoretical Shockley-Queisser limit. Two major issues need addressed, including disorder crystallization and unbalanced interface charge extraction, which limit further improvements in device efficiency. Herein, we develop a thermally polymerized additive as polymer template film, can form monolithic grain unique "Mortise-Tenon" structure after spin-coating hole-transport...
Abstract The efficiency of perovskite photovoltaics remains distant from their theoretical limits, primarily due to high photovoltage losses. Here a strategy is reported minimize voltage losses by reconstructing the surface into bilayer heterojunction (BLH) structure. Unlike conventional low‐dimensional capping layers, typically constrained few nanometers prevent low fill factors, this methodology facilitates more comprehensive reaction with defects, allowing substantial layer (≈50...
Abstract Dimethyl sulfoxide (DMSO) is commonly used as a solvent in the fabrication of perovskite solar cells. However, its strong coordination with iodoplumbate makes it difficult to remove during film formation, resulting defects and voids at perovskite‐substrate interface, which compromise efficiency long‐term stability. Here ethyl acrylate (EA), an unsaturated monomer that aids effective removal DMSO from introduce. EA forms complex DMSO, facilitates de‐intercalation, enhances...
Abstract Formamidinium lead iodide (FAPbI₃) perovskite solar cells (PSCs) hold immense potential for high‐efficiency photovoltaics, but maximizing their open‐circuit voltage ( V OC ) remains challenging. Targeting the inherently stable {111} c ‐dominant facets is a promising approach enhancing stability, formation typically suffers from high defect densities and disordered growth. This study introduces novel using an in situ polymerizable radical molecule, ATEMPO, as additive to address...
Despite the ongoing increase in efficiency of perovskite solar cells, stability issues have been a significant hindrance to its commercialization. In response this challenge, stepwise melting-polymerizing molecule (SMPM) is designed as an additive into FAPbI

For achieving high-performance p-i-n perovskite solar cells (PSCs), hole transporting materials (HTMs) are critical to device functionality and represent a major bottleneck further enhancing stability efficiency in the inverted devices. Three dopant-free polymeric HTMs developed based on different linkage sites of triphenylamine phenylenevinylene repeating units their main backbone structures. The curvatures affect morphology mobility polymers change crystallinity films. By using PTA-mPV...
