Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules (Adv. Funct. Mater. 47/2026)

Large-Area Perovskite-Organic Tandem Solar Module The cover image illustrates a nicotinic hydrazide-based interfacial modulation for realizing an aggregate-free self-assembled monolayer (SAM) with improved surface wettability and interfacial contact over a large area. The modified SAM-incorporated perovskite-organic tandem solar module with an active area of 16.41 cm2 shows a power conversion efficiency of 19.89%.
