Epitaxial Strategies for High Power Optically Pumped Vertical External Cavity Surface Emitting Lasers and Metamorphic Antimonide Solar Cells
Online Presentations | 05 Dec 2016 | Contributor(s):: Ganesh Balakrishnan
We present antimonide-based photovoltaic cells grown on GaAs and Silicon substrates for use as sub-cells in metamorphic multi-junction solar cells. These antimonide cells, based on GaSb, are designed to absorb near-infrared photons. The GaSb layer is grown on either GaAs or Silicon substrates.
