METHOD FOR APPLYING ELECTRICAL CONTACTS ON SEMICONDUCTING SUBSTRATES, SEMICONDUCTING SUBSTRATE AND USE OF THE METHOD

摘要

An electrical contact is applied on a semiconducting substrate, such as a solar cell. A layer of metallic powder is applied on the substrate. A laser beam is the guided over the substrate for local sintering and/or melting of the metallic powder. The non-sintered or non-melted metallic powder is then removed from the substrate.
