Abstract
Official abstract text for this publication.
A method includes depositing spacers at a plurality of locations directly on a back contact layer over a solar cell substrate. An absorber layer is formed over the back contact layer and the spacers. The absorber layer is partially in contact with the spacers and partially in direct contact with the back contact layer. The solar cell substrate is heated to form voids between the absorber layer and the back contact layer at the locations of the spacers.
