Photovoltaic cells illuminated with a monochromatic light source have revealed the highest ever reported photon-energy conversion efficiency. In this paper we investigate laser illuminated photovoltaic cells. III–V materials including GaInP, GaAs and GaSb were used to fabricate laser power converters. A special emphasis is given to the GaAs material. Here we report on the use of a lateral conduction layer which reduces the emitter sheet resistance. This solves the problem of ohmic losses due to…
