Impact of multi-busbar front grid patterns on the performance of industrial type c-Si solar cell

•Theoretical calculations (optimization) are carried out for the total front contact losses (viz. optical and electrical) of commercially available patterns solar cell.•The levelized cost of energy (LCOE) due to Silver (Ag) paste has also been estimated for production of 10 MW power.•The effect of increasing number of busbars on solar cell performance is analyzed here. The EM field distribution due to incident photon flux is also shown here using COMSOL Multiphysics simulation software.
