Publication number: 20210384366Abstract: Approaches for the metallization of solar cells and the resulting solar cells are described. In an example, a method of fabricating a solar cell involves forming a barrier layer on a semiconductor region disposed in or above a substrate. The semiconductor region includes monocrystalline or polycrystalline silicon. The method also involves forming a conductive paste layer on the barrier layer. The method also involves forming a conductive layer from the conductive paste layer. The method also involves forming a contact structure for the semiconductor region of the solar cell, the contact structure including at least the conductive layer.Type: ApplicationFiled: August 17, 2021Publication date: December 9, 2021Inventors: Richard Hamilton Sewell, David Aaron Randolph Barkhouse, Junbo Wu, Michael Cudzinovic, Paul Loscutoff, Joseph Behnke, Michel Arsène Olivier Ngamo Toko
