TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The step of contacting the photovoltaic cell with the light induced plating composition comprises immersing the photovoltaic cell in the light induced plating composition. Preferred Components: The light induced plating composition comprises a complexing agent for the silver ions. The source of soluble silver ions is silver methanesulfonate, silver acetate, silver sulfate (all preferred), silver oxide, silver nitrate, and/or silver citrate. The concentration of soluble silver ions is 1-35 g/l.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The solubilizing agent: is glyoxylic acid, glycolic acid, lactic acid, any alpha - or ortho-hydroxycarboxylic acids, aliphatic dicarboxylic acids, and/or hydroxy-polycarboxylic acids; comprises tartaric acid, citric acid or its salt. The concentration of the solubilizing agent is 1-150 (preferably 10-30) g/l. The complexing agent is optionally substituted hydantoin (preferred), cyanide, optionally substituted succinimide, uracil, thiosulfate, and/or amines. The concentration of the complexing agent is 20-150 g/l. The pattern comprises: metal on the front side of the solar cell comprising current collection lines and busbars printed on it; or metal comprising printed silver paste. The light source is halogen lamps, incandescent lamps, fluorescent lamps, LED, or mercury lamps. EXAMPLE - Solar cell pieces were plated with the solutions (comprised of silver acetate (17.5 g/l), hydantoin (52.5 g/l), boric acid (22.8 g/l), methanesulfonic acid (8.7 g/l), Rochelle salt (39.5 g/l), glyoxylic acid hydrate (52 g/l), and potassium hydroxide (to adjust the pH to 8.8)). The lines on the front side consisted of printed silver paste and had an average of 82 mu width as measured by a top-down optical microscope. Cell piece was plated in the solution for 8 minutes at 45 degrees C in a clear glass beaker while irradiated the front side using a 250 W lamp from a distance of 5 inches. The cell pieces were then rinsed with deionized water and dried, to obtain the metalized photovoltaic solar cell with the layer of metal deposited on it.
