Heterojunction technology: The path to high efficiency in mass production

Heterojunction technology is currently a hot topic actively discussed in the silicon PV community. Hevel recently became one of the first companies to adopt its old micromorph module line for manufacturing high-efficiency silicon heterojunction (SHJ) solar cells and modules. On the basis of Hevel’s own experience, this paper looks at all the production steps involved, from wafer texturing through to final module assembly.
