A researcher in <semiconductor> devices whose joint work with <H. J. Hovel> demonstrated <heterojunction> <solar cells> made from <gallium arsenide> and an aluminum-containing alloy. The additional layer admits useful light while reducing <surface recombination> and electrical resistance. Their 1972 experiment illustrates why an efficient <solar cell> depends on controlling what happens to generated carriers at a surface, as well as on absorbing incident light.<High-efficiency Ga1-xAlxAs-GaAs solar cells by Jerry M.
