Wearables, IoT devices; direct primary power for batteries and electronics
Integrates two space-grade triple-junction GaAs cells (average efficiency 31% at AM0, 1 sun, 136.7 mW/cm², 25°C) onto a compact PCB with EVA and TPT encapsulation and a circuit-integrated design, providing high reliability under various conditions. For terrestrial use, the nominal output is 4.5 V at 14.8 mA, suitable for wearables and IoT applications.
