In 2010, about 2000 t of Ag were used in the contact metallization of silicon wafer‐based photovoltaics, consuming approximately 7% of the total annual world Ag supply. With the growth of the photovoltaic industry by 10 times/decade over coming decades not out of the question, Ag supply is clearly an impending material resource issue. Minimum requirements for screen‐printed cells are analyzed with the conclusion that design changes will likely be required over the coming decade to reduce use.
