Abstract In organic solar cells (OSCs), electron transport layer (ETL) materials are typically designed with highly polar groups to lower the work function (WF) of cathode and ensure solvent orthogonality. However, increased surface energy associated these results in significant hygroscopicity poor interfacial contact active layer, posing a challenge for interlayer engineering that must balance device efficiency stability. Herein, two novel arylene diimides (PDI‐P NDI‐P) developed side chains end‐capped piperazine groups, as opposed commonly used amine groups. As ETLs, not only exhibit excellent conductivity but also effectively WF silver cathode. Compared amine‐functionalized perylene diimide (PDI‐N), piperazine‐functionalized (PDI‐P) exhibits reduced hygroscopicity, resulting improved wettability decreased moisture sensitivity. These characteristics contribute enhanced The PDI‐P ETL is compatible various high‐performance acceptor materials, achieving high efficiencies across wide thickness range ≈7 30 nm, maximum 19.8%. findings highlight great potential an high‐efficiency stable OSCs.

Abstract Semitransparent organic photovoltaics (ST‐OPVs) hold great promise for building‐integrated applications but encounter a critical trade‐off between power conversion efficiency (PCE) and visible transparency. This work addresses this challenge by introducing novel theoretical framework that synergistically combines optical modeling material design. A piecewise Gaussian absorption model has been developed to accurately simulate asymmetric spectral characteristics of materials. enables the virtual screening potential donor‐acceptor configurations, identifying two optimal configurations: narrow‐narrow (N + N) system wide‐narrow (W system, which achieve superior balance PCE High‐throughput bilayer coupling layers further enhances light utilization 9.8% 9.3% through optimized management. study bridges properties engineering, providing predictive tool ST‐OPV optimization guide development high‐performance, visually transparent solar technologies.
