Electrochemical deposition of contact materials in postgrowth technology of photovoltaic converters

Investigations and modeling of ohmic contacts electrochemical deposition process in postgrowth technology of photovoltaic converters fabrication have been carried out. The technology of Ag/Au contact system galvanic deposition at vertical and horizontal position of heterostructure and anode in the electrolyte has been developed. The increase of contact system deposition uniformity up to $\sim$ 95% at the thickness of contact bus-bars $\sim$ 5 $\mu$m on the heterostructure area with 4 inch diameter has been archived.
