Research Abstract

Vertical junction type organic photovoltaic cells having a pn junction formed perpendicularly to a light irradiated surface were fabricated. Short-circuit photocurrent density of 8.5 mA/cm^2 were observed under simulated solar illumination.
Three-layered organic solar cells incorporating a codeposited interlayer of fullerene and metal-free phthalocyanine, whose nanostructure was optimized by controlling the substrate temperature during coevaporation, showed a photoelectric conversion efficiency of 2.5%.
10 cm^2 area molecular photovoltaic cells have been fabricated incorporating transparent protection layer of naphthalene tetracarboxylic anhydride (NTCDA) which completely suppress electrical shorting.
