A method for manufacturing interconnected solar cells and such interconnected solar cells.

摘要

The invention relates to a method for making interconnected solar cells. The method has steps of a) providing a continuous layer stack on a substrate. The layer stack has a top electrode layer, a bottom electrode layer adjacent to the substrate, a photo-voltaic active layer and a barrier layer adjacent to the bottom electrode layer interposed between the top and the bottom electrode layer; b) selectively removing the top electrode layer and the photo-voltaic layer for obtaining a first trench exposing the barrier layer using a first laser beam with a first wavelength; c) selectively removing the barrier layer and the bottom electrode layer within the first trench for obtaining a second trench exposing the substrate using a second laser beam with a second wavelength, d) filling the first trench and the second trench with electrical insulating member.
