Abstract
A method of fabricating a solar cell is disclosed. The method includes the steps of forming a sacrificial layer on a silicon substrate, forming a doped silicon layer atop the sacrificial substrate, forming a silicon film atop the doped silicon layer, forming a plurality of interdigitated contacts on the silicon film, contacting each of the plurality of interdigitated contacts with a metal contact, and removing the sacrificial layer.
