The electrical and photovoltaic characteristics of spin coated thin films of poly (3-phenyl azo methine thiophene) (PPAT), sensitized with pyronine (G) (PYR) dye sandwiched between indium tin oxide (ITO) and aluminum (Al) have been investigated. The p-type conductivity and rectification ratio of PPAT increases with dye sensitization. The depletion layer width (W) of about 64 nm evaluated from the...
