DOI: 10.1016/j.jcrysgro.2020.125600

Abstract: Abstract In this study, we characterize the GaAs solar cells grown under different conditions using a custom-built atmospheric-pressure hydride vapor-phase epitaxy (HVPE) reactor. Under typical HVPE growth involving the decomposition of AsH3 to Asx, the… read more here.

DOI: 10.1016/j.tsf.2018.05.042

Abstract: Abstract Current thin-film GaAs solar cells typically have a completely metal covered rear side that functions as back contact, rear mirror and stable carrier to the solar cell. However, the bottom contact layer, that typically… read more here.
