Abstract Perovskite solar cells (pero‐SCs) are highly unstable even under trace water. Although the blanket encapsulation (BE) strategy applied in industry can effectively block moisture invasion, commercial UV‐curable adhesives (UVCAs) for BE still trigger power conversion efficiency deterioration, and degradation mechanism remains unknown. For first time, functions of UVCAs revealed BE‐processed pero‐SCs, where small‐sized monomer easily permeates to perovskite surface, forming an...

Metal-semiconductor field-effect transistors (MESFETs) offer the advantages of efficient gate control and low power consumption due to large junction capacitance. However, strong Fermi-level pinning caused by metal-induced gap states makes it a great challenge build high-quality Schottky with energy barrier leakage current. Moreover, upper limit work function conventional metals is around 5 eV, which prevents formation wide depletion region reduction consumption. In this work, 2D semimetals...
High-efficiency organic solar cells (OSCs) are typically produced through spin-coating, restricting their application to small areas. Blade-coating, however, emerging as a promising method for large-scale production, yet faces challenges in film morphology optimization, which often leads reduced power conversion efficiency (PCE). This study delves into the influence of both liquid and solid additives on active layer blade-coated OSCs, comparing them with spin-coated counterparts, using...
