To realize an efficient photovoltaic device,one of the methods of creating a large interfacial area at which the effective dissociation of excitons occurs is to mix an electron donor material with an electron acceptor material.The new soluble conducting polymer-dye ROPPV(poly(2,5-dialkoxy-p-phenylene vinylene)/ N,N'-diphenyl glyoxaline-3,4,9,10-perylene tetracarboxylic acid diacidamide (PV) composite was prepared.Electrical and optical properties of soluble conducting polymer composite films,and current-voltage(I－V) characteristics and photocurrent spectra of photovoltaic cells are discussed.Our results show that the soluble conducting polymer-dye composite represents a new class of organic semiconducting materials that can be used to manufacture photovoltaic cells.
