Abstract Quasi‐2D perovskite thin films hold great promise for creating highly efficient and stable optoelectronic devices. Regulating the intermediate phase during crystallization is crucial determining film quality, directly impacting device performance. In this study, bifunctional molecule L‐carnitine introduced into quasi‐2D precursor solution to modulate crystallization. The results demonstrate that strong coordination between PbI 2 effectively impedes combination of dimethyl sulfoxide (DMSO), preventing formation ·DMSO phase. This elimination mitigates potential hazards associated with DMSO escape subsequent annealing, significantly enhancing quality. Furthermore, groups in interact perovskite, passivating defects thermal illumination stability. As a result, L‐carnitine‐modified photodetector exhibits outstanding performance, responsivity 2724 mA W −1 detectivity 9.10 × 10 Jones. research proposes novel strategy regulate phases passivate synergistically, enabling production high‐quality high‐performance

The SnO2 electron transport layer (ETL), fabricated by spin-coating from commercially available aqueous colloidal dispersion, is widely used in perovskite solar cells (PSCs). In this study, we demonstrate that the relative humidity (RH) during significantly affects PSC performance. Spin-coating at higher RH levels leads to formation of rougher ETL surfaces with numerous pinholes, which results reduced performance due partial contact between light absorber and indium tin oxide (ITO) electrode layer. contrast, smoother, pinhole-free are achieved lower levels, reducing ITO/perovskite thereby enhancing A double-layer architecture proposed further improve architecture, first layer, 0% a smooth surface, minimizes direct contact, while second 80% enhances extraction increasing SnO2/perovskite interface area. These findings underscore importance controlling achieve PSCs better reproducibility.

Perovskite solar cells (PSCs) with inverted structures have gained significant attentions in the field of photovoltaics. NiO is one commonly explored hole transport materials (HTMs) due to its excellent chemical stability compared organic materials. Pure an insulator, but presence nickel vacancies introduces formation Ni3+ ions that give rise p-type semiconductor properties. However, low conductivity and poor interfacial contact between perovskite thin films still pose challenges achieving high-performance PSCs. To overcome these issues, this study used potassium acetate as a source into precursor doped (K+) nanocrystals. The introduction K+ induces ions, thereby increasing mobility NiO. Furthermore, K+-doped demonstrated better interface film, facilitating efficient separation photo-generated charges strong photoluminescence quenching effect. Experimental results optimal concentration doping 3 mol%, PSCs prepared exhibited increase efficiency, from 15.15% 16.75%, primarily attributed improvements short-circuit current density fill factor. These highlight importance enhanced achieved through for charge carrier collection, effectively addressing limitations
