AI Technical Summary
Existing electrode manufacturing methods for solar cells face challenges such as limited electrode width due to laser film perforation size, leading to increased laser damage, blocked sunlight incidence, and reduced conversion efficiency, as well as inefficiencies in vertical electroplating that hinder scale production.
A method involving perforating a film layer to form holes or grooves, growing a seed layer with a main component of Al and improved components like Mo, Ni, Ti, W, Cr, Mn, Pd, Bi, Nb, Ta, Pa, and V, and using horizontal electroplating to form electrodes, ensuring wider electrode widths and improved adhesion.
The method allows for increased electrode width, reducing line resistance and preventing electrode detachment, while enabling efficient scale production through streamlined horizontal electroplating.
