Abstract

The present invention relates to cost effective production methods 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.
