Abstract
A method for fabricating a solar cell commences by bonding a first metal-coated substrate to a second metal-coated substrate to provide a bonded substrate. The bonded substrate is then coated with a first precursor solution to provide a coated bonded substrate. Finally, the procedure de-bonds the coated bonded substrate to provide a first solar cell device and a second solar cell device. A system for fabricating the solar cell comprises a first precursor solution deposition system containing a first precursor solution for deposition on a substrate, a first heating element for heating the substrate after deposition of the first precursor solution, a second precursor solution deposition system containing a second precursor solution for deposition on the substrate, and a second heating element for heating the substrate after deposition of the second precursor solution.
