  • Solar Power Satellite – Minimising the Mass Required

    This 2014 preprint describes a way of pushing photovoltaics to 69% efficiency: Optical Refrigeration for Ultra-Efficient Photovoltaics [NB: The trio of authors have produced multiple papers since, along similar lines] The operating temperatures are high, but doable with concentrators and the right materials. That makes it very attractive for Solar Power Satellite deployment, so long […]
