Abstract
We have prepared new soluble conducting polymer-dye composite and photovoltaic cells with three different architectures using soluble conducting polymer (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/Al) and a double-layer structure (ITO/CP + PV/PV/Al) as well as a three layer structure (ITO/CP+C 60 /CP+PV/PV/Al). Electrical and optical properties of soluble conducting polymer-dye composite, current-voltage (I/V) characteristics and photocurrent spectra have been discussed. Our results show that soluble conjugated polymer composite represents a new class of organic semiconducting materials that can be used to manufacture photovoltaic cells.
