Experimental Study of Some Effective Surface Parameters of Crystalline SiliconSolar Cell for Getting Better Performance

This experimental study focoused on the analysis and optimization of some effective surface parameterlike reflectance, series resistance, fill factor and surface recombination velocity to enhance theperformance of Si solar cell. Near sub wave length structure is introduced to overcome the contactproblem of nano texturization where reflection loss is less than micro texturization. Screen printingtechnique is the low cost industrial established process but it also raises some unwanted problem whichreduces the fill factor. Light Induced Plating (LIP) of c-Si solar cell is a critical process generallyleading to increase in fill factor and efficiency associated with marginal reduction in short circuitcurrent (Jsc). In this paper, the increase in Jsc is reported at the LIP treated solar cell due tounintentional deposition of silver nanoparticle on the surface of solar cell. The array of silvernanoparticle on the Si surface results into plasmonic effect as evidence by the reduction of reflectanceand increase in external quantum efficiency without depositing added nano particles. Also, new type oftexturization, contact optimization and better LIP treatment are reported.
