Photosensitive properties of Perylene–Oxazine films, solution-deposited on doped silicon

Liquid phase deposition of chlorobenzene solutions containing Perylene and Oxazine, is used to grow films made of quasi-parallel wire-like microstructures. Films form, when deposited on n-doped monocrystalline silicon wafers, photosensitive heterojunctions with a spectral response that closely resembles Perylene–Oxazine absorption. Photoelectric properties of the heterojunctions are investigated employing current versus voltage measurements, which are performed in the dark and under white light with a power density range of 0.1 mW/cm2 to 1.0 mW/cm2.
