ABSTRACT

With the advent of nanocrystalline based approach problems like performance degradation due to Pb diffusion in CdS/PbS solar cells can be solved. In this study an effort has been made to improve the performance of CdS/PdS thin film based devices, by doping with rare earth Pr. In this study undoped and Pr doped CdS thin films were prepared using Chemical Bath deposition and characterized for structural, optical and Morphological properties on pre cleaned glass and ITO coated glass plates. The PbS thin films were prepared system by chemical bath deposition over the CdS nano thin film layers grown over ITO glass plates and their photovoltaic properties were studied using Photocurrent–voltage measurements at AM 1.5 at an illumination of 100 mW/cm2. The results are reported. The increase of Pr concentration in the CdS layer has produced considerable enhancement in the microstructural and optical properties leading to a performance efficiency. The possible mechanism are also discussed.
