Process for coating the surface of the semiconductor substrate of a solar cell

摘要

In a process for coating the surface of the semiconductor substrate (2) of a solar cell (4) with a metallisation layer (3) applied by autogenous flame spraying with a spray jet (20), a transverse stream of gas (22) is blown into the spray jet (20) during the application of the metallisation layer (3) in order thereby to reduce the energy load imposed on the semiconductor substrate (2).
