摘　　要：A solution-processed bulk heterojunction photovoltaic cell is fabricated based on poly[(2-methoxy,5-octoxy)-1,4-phenylenevinylene](MOPPV)-single walled carbon nanotube(SWNT)-ZnSe quantum dots.The surface morphology shows the formation of an interpenetrating network between well-dispersed SWNTs and ZnSe in the MOPPV matrix.A blue-shifted absorption band indicates the strong electron interaction between SWNTs,ZnSe and MOPPV.A marked increase in the short-circuit current and power conversion efficiency(PCE)of ITO/PEDOT:PSS/MOPPV-SWNT-ZnSe/LiF/Al devices was achieved and compared with that without SWNTs.Results indicate that the enhanced performance is contributed by a high photocurrent due to efficient exciton dissociation and increased mobility for carrier transport in the SWNT pathway.
