Optimizing cadmium (Cd) alloy solar cells with sputtered copper-doped zinc telluride (ZnTe:Cu) back contacts in the presence of hydrogen
A method of manufacturing a cadmium (Cd) alloy transmissive solar cell is provided. The method includes pumping a vacuum chamber to a base pressure and pumping the vacuum chamber to a sputtering pressure. The method includes providing into the vacuum chamber a first gas at a rate that balances a flow of the first gas in and out of the vacuum chamber with respect to the sputtering pressure and heating a surface of a partially manufactured cadmium (Cd) alloy transmissive solar cell within the vacuum chamber to a calibrated deposition temperature. The method includes providing into the vacuum chamber a second gas including at least a hydrogen gas (H.sub.2) at a proportional rate to achieve a target gas mix while maintaining the sputtering pressure and depositing a target material onto the surface to form a back contact section of the cadmium (Cd) alloy transmissive solar cell.
