Abstract | For the commercial exploitation of organic solar cells significant improvements in power conversion efficiency must be achieved. Whilst state-of-the-art organic solar cells based on nano-scale phase separated polymer blends have recently achieved cell efficiencies of - 5%, this is only half the prerequisite efficiency for market entry. The low efficiency of charge carrier extraction in this type of organic solar cell is a major obstacle to further improvements in power conversion efficiency, a problem which is exacerbated by the requirement to increase the thickness of the photoactive organic layer in order to harvest more of the incident light. This proposal seeks to engineer scalable nano-structured electrodes with the potential to dramatically improve the efficiency of charge carrier extraction by removing charges close to the point of generation along highly conductive pathways. Candidate materials include multi-wall carbon nanotubes and nano-structured conducting polymers supported on indium-tin oxide coated plastic substrates. These high transparency and flexible composite electrodes are a compelling alternative to conventional smooth electrodes and do not complicate the process of cell fabrication. The successful development of this new class of electronic material is expected to greatly increase the prospects of organic solar cells realizing their potential as an economically viable path to harvesting energy from sunlight | |
