Currently, achieving both high efficiency and long‐term stability is crucial for the successful application of perovskite solar cells (PSCs). Grain boundary (GB) defects significantly impact PSCs, passivating these GBs remains a major challenge. Herein, surfactant dodecyltrimethylammonium chloride (DTAC) dissolved in low‐polarity chlorobenzene (CB) at 58 °C to modify interface MAPbI 3 film, DTAC reacts with film surface generate protective layer that can be covered on grains, effectively reducing expose GBs. Additionally, hydrophobic alkyl chains DTA + strong chemical bond between Cl − Pb 2+ ions further enhance resistance heat, moisture, oxidation. Due passivation iodine vacancy defects, photo‐stability unencapsulated devices improved. By crystals, power conversion low‐temperature carbon‐based PSCs treated by 15.03% compared 13.97% control device. This study offers another referable strategy enhancing thermal, light, oxygen materials while considering photovoltaic performance devices.

Studies indicated that two-dimensional (2D) metal halide perovskites (MHPs) embodied with three-dimensional (3D) MHPs were a facile way to realize efficient and stable perovskite solar cells (PSCs) photodetectors (PPDs). Here, high-performance PSCs PPDs, which are based on 2D/3D bilayer thin films, where the 2D created by binary conjugated organic cations, reported. Systemically studies reveal above novel films possess an enlarged crystal size, balanced charge transport, reduced carrier recombination, smaller charge-transfer resistance, accelerated charge-extraction process compared single cation. As result, film exhibit power conversion efficiency of 22.76%. Moreover, unencapsulated dramatically enhanced stability those In addition, PPDs projected detectivity 1016 cm Hz1/2/W linear dynamic range 108 dB at room temperature.

In this study, we investigated the impact of benzophenone (BP), a small molecule additive, on performance and stability inverted perovskite solar cells (PSCs). Specifically, introduced BP into precursor solution FAPbI3 to fabricate PSCs with an ITO/PEDOT:PSS/BP:FAPbI3/PCBM/C60/PCB/Ag architecture. The incorporation optimum concentration 2 mg mL–1 significantly enhanced power conversion efficiency (PCE) PSC from 13.12 18.84% negligible hysteresis. Notably, BP-based retained ∼90% their initial PCE after being stored in ambient air 30% relative humidity at 25 °C for 700 h. contrast, control devices showed rapid degradation, retaining only value within 300 h under same conditions. We attributed superior grain boundary passivation film. improvement was mainly intermolecular interaction between O-donor Lewis base material both Pb2+ FA+ FAPbI3. This effectively suppresses trap-assisted recombination promotes δ-phase photoactive stable α-phase Overall, our findings suggest that is promising additive improving PSCs.

Current development of inverted p-i-n perovskite solar cells (PSCs), with nickel oxide as the hole transport layer, is progressing toward lower net costs, higher efficiencies, and superior stabilities. Unfortunately, high density defect-based traps on surface films significantly limits photoelectric conversion efficiency operational stability cells. Finding cost-effective interface modifiers crucial for further commercial PSCs.

Perovskite solar cells (PSCs) have emerged as a promising photovoltaic technology due to their long carrier diffusion lengths, tunable bandgaps, and high light absorption coefficients. However, instability remains significant barrier commercialization. In this study, we introduce two carbonyl small molecule additives with varying fluorine atom counts: 4,5-difluoro-phthalic anhydride (2FPA) tetrafluorophthalic (4FPA). The atoms groups interact passivate defects in the perovskite structure. strong interaction between 4FPA facilitates slow crystal growth effective defect passivation, significantly suppressing nonradiative recombination enhancing transport efficiency. Consequently, power conversion efficiency (PCE) of PSCs incorporating has improved from 21.49 23.21%. Additionally, additive FA+ form hydrogen bonds coordinate Pb2+, thereby device stability. unencapsulated conditions, after approximately 1000 h ambient air 50 60% humidity, retains 87% its initial
