Abstract

A method of manufacturing a solar cell by providing a first substrate; depositing on a first substrate a sequence of layers of semiconductor material forming a solar cell including at least a top subcell and a bottom subcell; mounting a surrogate substrate on top of the sequence of layers adjacent to the bottom subcell; removing the first substrate to expose the surface of the top subcell; removing the surrogate substrate; and holding the solar cell on a vacuum chuck to support it for subsequent fabrication operations, such as attaching interconnects to the solar cells to form an interconnected array.
