Abstract
Textured semi-conductor devices, such as macro textured buried-contact solar cells, are produced with special front contact trenches to increase efficiency and decrease costs. In order to produce the front contact trenches, front channels and narrower metallization grooves are cut in the semi-conductor body. The front contact trenches are plated to form attractive conductive buried contacts comprising flush metallization fingers and bus bars.
