L2M – Next-Generation Multisource Thermo-Photovoltaic Receivers for Wireless Power Transmission Networks

We’re developing the first high-efficiency, ultra-long-range, multi-source thermophotovoltaic (TPV)-based wireless power transmission (WPT) receiver, designed to convert laser beams into electricity without relying on fragile PV surfaces. It uses a spectrally selective absorber to convert laser into tailored thermal emission, matched to low-bandgap GaSb cells. Unlike traditional laser WPT systems, it performs effectively in space, underwater, harsh environments, and ultra-long distances, where cables, batteries, or PV-based WPT fail or lead to high losses, costs, and oversized infrastructure. With low beam divergence, low atmospheric attenuation, spectral and laser flexibility, uniform high-power density tolerance, thermal buffering, and photon recycling, our system de-livers unmatched efficiency, scalability, and mission adaptability. From drones and satellites to deep-space and subsea infrastructure, this technology redefines untethered power delivery across Earth, orbit, and beyond.
