The tuning of vertical morphology is critical and challenging for organic solar cells (OSCs). In this work, a high open-circuit voltage (VOC ) binary D18-Cl/L8-BO system is attained while maintaining the high short-circuit current (JSC ) and fill factor (FF) by employing 1,4-diiodobenzene (DIB), a v...
