Polycrystalline MBE-Grown GaAs for Solar Cells

Research output: Contribution to conferencePaper


This paper will discuss initial studies of thin-film GaAs grown by molecular-beam epitaxy for use in developing a thin-film GaAs solar cell. Photocurent and photoluminescence intensity are related to the material morphology as a function of growth conditions. Growth temperature and V/III ration have a dramatic effect on the photocurrent. However, it seems likely that even after optimizing suchgrowth parameters, it will be necessary to provide substrates that can provide templates to enhance grain size from the start of thin-film growth.
