METHOD FOR METALLIZATION OR METALLIZATION AND INTERCONNECTION OF BACK CONTACT SOLAR CELLS

摘要

The present invention relates to cost effective methods for metallisation and or metallisation and interconnection of high efficiency silicon based back-contacted back-junction solar panels and solar panels thereof having a multiplicity of alternating rectangular emitter- and base regions on the back-side of each cell, each with rectangular metallic electric finger conductor above and running in parallel with the corresponding emitter- and base region, a first insulation layer in-between the wafer and finger conductors, and a second insulation layer in between the finger conductors and cell interconnections.
