Metallization Method for Interdigitated Back-Contact Silicon Solar Cells Employing an Insulating Resin Layer and a Ti/Ag/Cu Metal Stack

Interdigitated back-contact (IBC) silicon (Si) solar cells are attracting increased attention due to the potential of higher efficiency that comes from eliminating front-surface shading. However, as sources of recombination loss continue to be reduced due to improved processing and use of high-quality n-type wafers, parasitic absorption in the rear metal can limit cell performance.
