Abstract

Polymer solar cells have evolved as a promising cost-effective alternative to silicon-based solar cells.However, low efficiency of these plastic solar cells limits their feasibility for commercial use. The efficiencies ofpolymer photovoltaic cells got a major boost with the introduction of the bulk heterojunction (BHJ) conceptconsisting of an interpenetrating network of electron donor and acceptor materials.In this work we describe the preparation of BHJ organic solar cells using blend films of poly[4,4’-bis(alkylsulfanyl)-2,2’-bithiophene] (P3ST) and 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C61 (PCBM). Photovoltaic cells wereprepared with a layer sandwiched between electrodes with different work functions. The electrical performance ofthe devices were compared with the corresponding one prepared using a blend of commercial poly(3-hexylthiophene)(P3HT) and PCBM. The quantum efficiency of the device fabricated with P3ST/PCBM blend shows a betterresponse in the visible region compared to the one with P3HT/PCBM.
