• Impact of the organic layer thickness on photovoltaic performance.
• The photovoltaic effect was investigated the Al/Azure C/p-Si heterojunctions.
• The device measured in dark and light conditions under the 50 mW/cm2 light source.
The current–voltage (I–V) and capacitance–voltage (C–V) characteristics of Al/Azure C/p-Si heterojunction fabricated with spin coating system have been investigated under illumination conditions, coating thickness at room temperature. Some heterojunction parameters such as ideality factor and barrier height were obtained to be 1.10, 1.15, and 1.26, and 0.57 eV, 0.64 eV and 0.65 eV for undoped, doped 2 μl/cm2, and 4 μl/cm2, respectively from the current–voltage measurement by thermionic emission current equation. It was observed that the ideality factor, barrier height and photovoltaic performance have increased and the device capacitance decreased with increasing organic layer thickness.
