Improvement in the Power Conversion Efficiency of Bulk Heterojunction Photovoltaic Device via Thermal Postannealing of Subphthalocyanine:C70 Active Layer
The authors report an efficient organic photovoltaic device based on subphthalocyanine (SubPc):C70 bulk heterojunction (BHJ) via the postannealing treatment. The power conversion efficiency is improved from 4.5% to 5.5% due to the increase in short-circuit current density (JSC) from 8.8 to 12.7 mA/c...
