Abstract
Organic photovoltaic properties were studied in $CuPc/C_{60}$ and $ZnPc/C_{60}$ heterojunction structure by varying the organic layer thicknesses. Current density-voltage characteristics of organic photovoltaic cells were measured using Keithley 236 source-measure unit and a 500 W xenon lamp (ORIEL 66021) for a light source. From the analyses of current-voltage characteristics such as short-circuit current density, open-circuit voltage and power conversion efficiency, optimum thickness of the organic layer were obtained.
