Abstract Organic solar cells (OSCs) with the conventional configuration usually use polyethylenedioxythiophene:polystyrene sulfonate (PEDOT:PSS) as hole‐transporting layer (HTL); however, its acidity tends to affect performance and long‐term stability of devices. Therefore, replacing PEDOT:PSS other more stable HTLs is essential for realizing practical applications OSCs. To achieve this goal, a simple low‐cost vanadyl oxalate (VOC 2 O 4 ) identified HTL facilitate high power conversion...
