Surface Plasmon from the metal nanoparticles is responsible for the light scattering which make them striking for light trapping in photovoltaic applications. Chemical synthesis of colloidal nanoparticles is one of the low-temperature; low-cost, easily scalable technique can produces the highest monodispersion nanostructure. Similarly, electrodeposition from non-aqueous bath allows depositing layer at higher bath temperature which may be helpful to enhance the crystallinity and particle size. In this study we demonstrate a active SPR effect with gold (Au) nanoparticles onto the Cu(In,Ga)Se2 (CIGS) active semiconductor layer. The CIGS layers is fabricated onto the fluorine doped tin oxide (FTO) coated glass substrates by electrodeposition technique from non-aqueous electrolyte. The Au nanoparticles are deposited onto the CIGS layer with dip coating for different durations. The optical, morphological, electrical and optoelectronic properties of gold nanoparticle implanted in the CIGS thin film were studied and demonstrated the improvement in the solar cell parameters.
