Properties of conducting polymer-dye composite and photovoltaic characteristics of junction devices

We have prepared new soluble conducting polymer/dye composite and photovolt aic cells with three different architectures using soluble conducting polym er (CP) as hole transport material and perylene derivatives (PV) as electro n transport material. These architectures comprise single-layer (ITO/CP-PV/ Al) and double-layer (ITO/CP-PV/PV/Al) as well as three-layer (ITO/CP-C-60/ CP-PV/PV/Al) structures. Electrical and optical properties of soluble condu cting polymer composite film and current-voltage characteristics and photoc urrent spectra of photovoltaic cells are discussed. The results show that t he soluble conducting polymer-dye composite represents a new class of organ ic semiconducting material that can be used to manufacture photovoltaic cel ls.
