Abstract
This experimental study mainly focused on the improvement of solar cell front contacts. Industrial solar cell's front contacts are made by screen printing method using Ag-paste material, but there are some processing steps drawbacks. Mainly on the surface of the front contacts create some unwanted pores those increases the series resistance and edge of the front contacts form unwanted Ag-paste dots and different structures which increase optical loss. By optimizing the concentration of solution, light intensity, and chemical treatment in Light Induced Plating (LIP) solar efficiency increases up to~1. 2% is possible.
