Abstract

In this paper we demonstrate an efficient inverted polymer bulk heterojunction (BHJ) solar cells using solution processed interfacial layer by mixing zinc oxide (ZnO) with cesium carbonate (Cs₂CO₃) for ideal electron extraction and transport. The optimized inverted BHJ solar cell with n-type mixed (ZnO:Cs₂CO₃) electron transport layer and blend of poly (3-hexylthiophene):Indene-C60 bisadduct as a photoactive layer shows a power conversion efficiency as high as 5.29%. This performance enhancement is attributed to improved interfacial contact between photoactive layer and electron extraction layer, low leakage current, and a suitable surface morphology for electron extraction and transport.
