Abstract Organic photovoltaic (OPV) cells based on a polymer/fullerene bulk-heterojunction (BHJ) active layer have emerged as promising, next-generation energy sources arising from their attractive properties: flexibility, low weight, and potential for low-cost, high-throughput manufacturing. Considerable efforts to develop new materials, device architectures, and processing techniques, have led to dramatic improvements in power conversion efficiencies (PCEs). One of the most important issues for enhancing the power conversion efficiency (PCE) of organic photovoltaic cells (OPVs) has been the development of -conjugated polymers that exhibit broad visible wavelength absorption, high charge carrier mobility, suitable energy level matching of frontier orbitals with those of the electron acceptor, and appropriate chain orientation that form an optimum pathway for the charge carriers to the electrodes. In this presentation, I will talk about recent progress on new donor-acceptor type conjugated polymers for organic photovoltaic cells conducted in our research lab.
