摘　　要：Organic photovoltaic cells(OPVs) have attracted more and more attention due to its highly potential application to solve the energy crisis considering its advantages,such as low cost and ease of large area production.The power conversion efficiency(PCE) of OPVs has undergone a more than nine-fold increase from ～1.0% by Tang in 1986 to 9.2% in 2010 announced by Mitsubishi Chemical.The major challenges of obtaining high efficiency OPVs are the synthesis of new narrow band gap materials,controlling molecular arrangement,designing novel configuration cells for better photon harvesting in the active layer.In the article,we summarized the recent progress of novel narrow band gap photovoltaic materials and the effective methods to control the morphology of donor and acceptor in the blend films for high performance of OPVs.Organic photovoltaic cells （OPVs） have attracted more and more attention due to its highly potential application to solve the energy crisis considering its advantages, such as low cost and ease of large area production.
