Properties of conducting polymer donor-acceptor composite films and photovoltaic characteristics of junction devices

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