An improved process for making solar cells could allow manufacturers to cut the amount of silicon needed in half. Since silicon can account for about three-quarters of the cost of conventional solar cells, this could significantly lower the price of solar power. The technique can reduce the amount of other materials used and improve solar-cell performance.
The process uses ink-jet printing to make electrical connections within a solar cell, replacing the existing screen-printing process. Because the ink-jet method is more precise, it can use less material for these connections. Also, because the printheads don't make contact with the silicon, the method works with thinner silicon wafers.
