New publication from the SUNLAB: Solar Energy Materials and Solar Cells

Is it possible to grow a high-efficiency photovoltaic device on a broadband back reflector? The SUNLAB’s latest publication in Solar Energy and Solar Cells, with recent PhD graduate Gavin Forcade as first author, makes progress toward this goal. In this collaboration between researchers at the University of Ottawa and the University of Waterloo, the authors fabricated thermophotovoltaic devices featuring an epitaxially grown highly n-doped InAs broadband back reflector with up to 93% reflectivity.
