Organic solar cells (OSCs) have attracted enormous interests in researcher due to its outstanding characteristics such as device structure tunability, lightweight, low cost, flexibility, and non-toxic. To improve the power conversion efficiency of OSCs, it’s required highly optical absorptive active photovoltaic material with the surface texturing medium, anti-reflection coating and plasmonic nanomaterials. In this study, we incorporated AgNPs anchored M13 bacteriophage (M13: AgNPs) into OSCs and investigated its effect as plasmonic optical enhancer. The as-fabricated OSCs exhibit device architecture as: ITO/ZnO/ M13: AgNPs /PTB7:PC71BM/PEDOT:PSS/Ag. After incorporating M13: AgNPs interfacial layer, the optical absorption and power conversion efficiency of OSCs was improved significantly. M13 bacteriophage interfacial layer could potentially be an excellent metamaterial for NPs anchoring in future optoelectronics application.
