[OWPT1-02(Invited)] High-irradiance photoconversion using multijunction photovoltaic devices

*John F. Geisz1, Danial J. Friedman1, Myles A. Steiner1, Ryan M. France1, Kevin L. Schulte1, Sarah Collins1, Darin Meeker1 (1. National Renewable Energy Laboratory)

Photovoltaic devices convert light into electrical energy at high-irradiance for concentrated solar photovoltaics, thermophotovoltaics and laser power converter applications. As the irradiance increases, the efficiency and economics improves until resistance, heating, or Auger recombination losses begin to dominate. We discuss strategies used to improve InGaAs PV performance at high irradiances.
