Paper Abstract

The selective removal of thin films along linear pattern for the serial connections of the cell is the issue addressed in this work. The two opposing cases of ultrafast absorption and of controlled thermal stress are investigated for their potentials in reaching a clean layer separation with sharp edges, to point out the optimal laser process for the different cell layers, that we think to be potentially superior with mechanical approaches.
