“…Organic solar cells (OSCs) have been rising as a promising energy-harvesting technology and attracted extensive attention in the photovoltaic field due to their advantages of low cost, large-area printing process, mechanical flexibility, lightweight, solution processability, and environmentally friendly compared to the conventional silicon-based solar cells [1][2][3][4]. However, the commercial applications of OSCs are still challenged by the insufficient power conversion efficiency (PCE).…”
