In addition, bulk heterojunction diodes made from ITO/PEDOT:PSS (CuPc-712+SQ-700+Pery-C7)/Al have been realized and studied by I–V characteristic measurements in the dark and under illumination (ITO is indium tin oxide; PEDOT:PSS is poly(3,4-ethylene dioxythiophene) oxidized (doped) with poly(4-styrene sulfonate)). Enhanced photosensitivity was observed in the photoreceptor made from the composite (CuPc-712+SQ-700+Pery-C7), which was interpreted in terms of the expansion of light absorption spectrum and to charge separation by the bulk heterojunctions. In addition, the presence of a thin PEDOT:PSS film at the ITO/(CuPc-712+SQ-700+Pery-C7) interface allows one to achieve a significant photovoltaic efficiency of 0.2%.
