| Description |
Copper (Cu) doped p-CdS nanoparticles have been synthesized via sol-gel method. The as-synthesized nano particles were successfully characterized and implemented for fabrication of Glass/ITO/n-ZnO/p-CdS/Al thin film photodiode. The fabricated device is tested for small (-1 V to + 1 V) bias voltage. Results verified that the junction leakage current within the dark is very small. During reverse bias condition, the maximum amount of photocurrent is obtained under illumination of 100 mu W/cm(2). Electrical characterizations confirmed that the external quantum efficiency (EQE), gain and responsivity of n-ZnO/p-CdS photodiode show improved photo response than conventional p-type materials for such a small bias voltage. It is therefore revealed that the Cu doped CdS nanoparticles is an efficient p-type material for fabrication of thin film photo-devices.
