Abstract
A process where a printed ink is placed onto a sacrificial ribbon. The ink is then converted to a metal film and transferred to a substrate, such as a silicon solar cell at very low temperatures. Further low-temperature processing may be utilized to form an ohmic contact. This process provides the speed and low-cost structure of ink and paste based processing with the diffusion control of vacuum deposited films.
