Abstract :
Light Induced Plating (LIP) of c-Si solar cell is a critical process generally leading to increase in fill factor and efficiency associated with marginal reduction in short circuit current (Jsc). In this paper, we report the increase in Jsc of LIP processed solar cell caused by unintentional deposition of silver nanoparticle on the surface of solar cell during LIP. The array of silver nanoparticle on the Si surface results into plasmonic effect as evidence by the reduction of reflectance and increase in external quantum efficiency.
