Fabrication of screen printed optoelectronic CdS/CdTe device

II-VI semiconductors have great importance in the fabrication and application of optoelectronic devices. CdTe is one of the most promising materials among photovoltaic materials. In this research work CdS/CdTe solar cell has been prepared using screen printing and sintering technique. Various factors affecting the surface morphology of CdS window layer were also investigated. Optical Microscopy, Scanning Electron Microscopy and Electrical characterization proved that best results can be achieved by increasing the sintering duration, the Mesh number and by CdCl2 doping. CdS/CdTe solar cell with an area of 8.8 cm2 was prepared. The Fill Factor was calculated to be 0.51, with Voc = 0.56 V and Isc = 31.5 mA. The efficiency was also measured and found to be 1.02%.
