CONVERSION OF METAL SEED LAYER FOR BUFFER MATERIAL

摘要

Approaches for forming solar cells with a converted seed layer as a buffer material and the resulting solar cells are described. In an example, a method of fabricating a solar cell includes converting regions of a seed layer disposed on a plurality of p-n junctions of the solar cell to form a pattern of interdigitated converted regions. The converted regions are configured to electrically insulate non-converted regions of the seed layer from each other and provide a barrier to a laser that is, in fabricating the solar cell, directed towards the seed layer such that the barrier substantially avoids degradation of at least the plurality of p-n junctions from the laser.
