InGaAs(P) materials optimized for thermal conversion
Enable multi-day energy storage with graphite thermal mass
Manufacturing capability established with proven 40%+ efficiency
TPV systems convert excess renewable electricity to heat, storing it in low-cost graphite blocks at temperatures exceeding 2,000°C. When electricity is needed, TPV cells convert the stored thermal energy back to electricity with unprecedented efficiency.
This technology enables cost-effective multi-day energy storage, addressing the critical need for long-duration grid storage to support renewable energy integration.
