THE STUDY OF STRUCTURAL, OPTICAL AND PHOTOVOLTAIC PROPERTIES OF NI (5%, 7.5% AND 10%) DOPED CDZNS NANOPARTICLES

Un-doped and Ni (5%, 7.5% and 10%) doped CdZnS nanoparticles (NPs) were prepared by the co-precipitation method at room temperature using the mercaptoethanol as a capping agent. J-V measurements were carried out for Ni-doped CdZnS NPs for the first time in this study, showed that Ni-doped CdZnS NPs can be utilized as sensitizers to improve the performance of solar cells. In addition to the photovoltaic properties, structural and optical properties of Ni-doped CdZnS NPs have been investigated. Study (XRD) on the structural properties showed that un-doped and Ni-doped CdZnS NPs have cubic (zinc blende) structure and the particle size of doped CdZnS NPs becomes smaller than un-doped CdZnS NPs. Optical absorption revealed that the absorption of Ni-doped CdZnS is  blue shifted compare to un-doped CdZnS NPs. Consequently, the results indicate that Ni-doped CdZnS NPs can be suitable material for photovoltaic applications
