Electrical and optical properties of new soluble conducting polymer/dye composite and junction device

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 N, N '- diphenyl glyoxaline -3, 4, 9 , 10 - perylene tetracarboxylic acid diacidamide (PV) as electron transport material. These architectures comprise a single-layer structure (ITO/CP+PV /A1) and a double-layer structure (ITO/CP+PV/PV/A1) as well as a three laye r structure (ITO/CP+C-60/CP+PV/PV/A1). Electrical and optical properties of soluble conducting polymer-dye composite, current-voltage (W) characterist ics and photocurrent spectra have been discussed. Our results show that sol uble conjugated polymer composite represents a new class of organic semicon ducting materials that can be used to manufacture photovoltaic cells.
