Abstract:
1. A method of electrodeposition, comprising: (a) establishing a plurality of ohmic contacts from a plurality of contacts pins to an underlying conductive layer through a semiconductor substrate film so as to cause negligible resistance from each contact pin, through the semiconductor substrate film, to the underlying conductive layer, said plurality of contact pins electrically isolated from a counter electrode; (b) electrodepositing a material from an electrolyte onto the substrate film to form a deposited film while the plurality of ohmic contacts are established; (c) withdrawing the plurality of contact pins from the deposited film to form a plurality of holes in the deposited film that are left in a plurality of positions from which the plurality of contact pins are withdrawn; (d) completely filling a portion or all of a plurality of holes, which were formed in the deposited film by the plurality of contact pins during the electrodepositing, with an insulating material to form a plurality of filled holes; and (e) forming a back contact layer over the deposited film to form at least one photovoltaic cell, wherein the insulation material remains in the filled holes after the back contact layer is formed.
