Nickel oxide (NiO) is a promising hole transport layer (HTL) that can be used to fabricate efficient, large‐scale inverted‐type perovskite solar cells (PSCs). However, depositing high‐quality on NiO substrates comparable those realized in the normal structure still presents challenge. Herein, pyridinium tetrafluoroborate (PyBF 4 ) additive introduced passivate intrinsic defects bulk films. The nitrogen Lewis base PyBF molecule interacts well with uncoordinated Pb 2+ cations, leading films minimized defects. Meanwhile, pseudohalide BF − fill halogen vacancies enable defect passivation. As result, precursor solution shows better reproducibility for high‐efficiency devices. optimal PSC based modification yields champion power conversion efficiency of 22.7% atomic deposited as HTL.

Indoor photovoltaics (IPV) plays a critical role in powering low‐consumption devices within the rapidly growing Internet of Things (IoT). Perovskite solar cells (PSCs) have demonstrated impressive indoor power conversion efficiencies (iPCEs) exceeding 40%, driven by advancements bulk and surface passivation techniques. These approaches mitigate trap states recombination losses, significantly enhancing device efficiency long‐term stability. This study investigates impact on PSC performance employing iodide‐based passivators—phenethylammonium iodide (PEAI), octylammonium (OAI), guanidinium (GUI)—alongside Lewis base molecule 1,3‐bis(diphenylphosphino)propane (DPPP), which, to best our knowledge, is introduced for first time n‐i‐p structured PSCs. SEM XRD analyses revealed that DPPP‐passivated samples exhibited superior morphological structural stability after ambient aging compared other passivations. Under 1000 Lx LED light illumination, achieved an iPCE 33.14%, closely approaching highest 34.47% obtained with PEAI. Furthermore, under thermal stress (85°C) T80 753 h. highlights layers low conditions, paving way more effective strategies advance perovskite materials IPV applications.

Abstract The copper content in sulfide significantly influences the material properties, potentially affecting interfacial non‐radiative recombination perovskite solar cells. Here, a simple ball‐milling strategy is used to obtain Cu‐poor (cupric sulfide, CuS) and Cu‐rich (cuprous Cu 2 S) nanoparticles (in which CuS S are dominant phases respectively, containing mixture of CuO/Cu(OH) species) from commercial cupric‐ cuprous‐sulfide powders respectively. resulting exhibit well‐crystallized hexagonal structure, suppressing formation harmful byproducts. Additionally, uniformly cover perovskite, effectively addressing residual PbI at grain boundaries constructing hole‐transport channel interface between spiro‐OMeTAD [2,2′,7,7′‐tetrakis (N, N‐di‐p‐methoxyphenylamine)‐9,9′‐spirobifluorene]. In contrast, non‐crystalline structure with excessive Their aggregation non‐uniform morphology on surface likely result charge‐controlled interactions big bond polarity cupric sulfide. Moreover, presence byproducts increases hydrophilic sites, weakening defect passivation compromising device performance. Consequently, cells using copper‐rich layers achieved champion power conversion efficiency (PCE) over 25% maintained ≈87% initial PCE after 2,300 h storage air, outperforming S‐based devices.
