de Vrijer, T. (author), Ravichandran, Ashwath (author), Bouazzata, Bilal (author), Smets, A.H.M. (author)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 vapor deposition (PECVD) processing could potentially provide a low-cost boost in conversion efficiency. A logical candidate for this low bandgap material is...journal article 2021
