Myles Steiner is a senior scientist working primarily on III-V multijunction solar cells for photovoltaic and thermophotovoltaic applications and for hydrogen and other solar fuels production via photoelectrochemical water splitting. He has worked on enhanced photon recycling and luminescent coupling in multijunction cells, growth and ordering of lattice-mismatched GaInP and GaInAs solar cells, mechanical stacking and lateral spectrum splitting multijunction designs, and the design and measurement of solar cells at elevated operating temperatures. He completed a bachelor’s degree in engineering physics at Queen’s University in Kingston, Ontario, followed by a master’s degree and doctorate in applied physics at Stanford University, where he studied superconductor-insulator phase transitions in homogenously disordered superconductors.
