A semiconductor researcher whose work with Jerry M. Woodall improved gallium arsenide solar cells using a heterojunction. A surface layer reduced surface recombination while transmitting much of the useful incident light. Comparing the spectral response before and after removing that layer exposed how surface losses suppress charge collection, connecting device efficiency with a measurable microscopic loss mechanism.[ref]
High-efficiency Ga1-xAlxAs-GaAs solar cells by Jerry M. Woodall and H. J. Hovel. pp. 379–381, especially Fig. 1 and discussion of layer removal
