Processing and Characterization of Novel low bandgap Ge Alloys for PV Applications: Path towards a new generation of high-efficiency PV devices

Low-cost multijunction photovoltaic devices are the next step in the solar energy revolution. Adding a bottom junction with a low bandgap energy material through plasma-enhanced chemical vapour deposition (PECVD) processing could provide a low-cost boost in conversion efficiency. A logical candidate for this low-bandgap material is germanium. A...
