Abstract Metal halide perovskites are ideal candidates for indoor photovoltaics (IPVs) due to their tunable bandgaps, which allow the active layers be optimized artificial light sources. However, significant non‐radiative carrier recombination under low‐light conditions has limited full potential of perovskite‐based IPVs. To address this challenge, an integration perylene diimide (PDI)‐based sulfobetaines as cathode interlayers (CILs) is proposed and impact varying alkyl chain length (from 1,2‐ethylene 1,5‐pentylene) between cationic anionic moieties examined. The respective four PDI materials synthesized almost qualitatively using a one‐step microwave‐assisted process. All them show adequate thermal stability energy levels suitable desired application CILs. Moreover, degradation temperature, LUMO level, conductivity, performance in model devices found change positively along with increase. Among tested derivatives, compound equipped longest (PDI‐C5‐S3) stands out its superior electrical conductivity enhanced ability lower silver work function. When incorporated into Cs 0.18 FA 0.82 Pb(I 0.8 Br 0.2 )‐based wide‐bandgap perovskite solar cells (PSCs), PDI‐C5‐S3 interlayer lead outstanding power conversion efficiency (PCE) 19.04% one‐sun illumination remarkable 40.72% 3000K LED (1000 lux) conditions.

Hole selective layers (HSLs) play a crucial role in the efficiency of organic photovoltaics (OPVs). Self-assembled monolayers (SAMs) offer powerful approach to engineer interfacial properties HSLs OPVs. In this work, we utilized 2-(9H-carbazol-9-yl)ethyl)phosphonic acid (2PACz) SAM modify ITO/MoO3 interface and surface MoO3, thereby forming multilayer HSLs. 2PACz regulates work function (WF) electrodes, leading more favorable energy level alignment, reduced resistance, facilitated charge carrier transport extraction. The resulting OPV devices demonstrated improved fill factor (FF) power conversion (PCE). Additionally, reduction defects effectively suppressed recombination, ultimately achieving maximum PCE 16.33%. This indicates that design composite with modification is an effective strategy for improving provides ideas further advancing development.
