A new wrinkle on an old technology – solid-state thermophotovoltaics (TPV) – could provide a high-efficiency alternative for directly converting high-temperature heat from concentrated solar thermal to utility-scale electricity.   New computer modeling suggests that high temperature TPV conversion – which captures infrared radiation from very hot surfaces – could one day rival combined-cycle turbine … Continue reading Molten Storage and Thermophotovoltaics Offer New Solar Power Pathway →
