Laser-driven optical harvesting systems

Laser-driven optical harvesting (LDOH) enables sustainable, 24/7 wireless power transfer, surpassing traditional solar methods. It efficiently delivers energy to remote receivers with high conversion efficiency, ideal for off-grid locations, hard-to-access sites, and industrial IoT applications. The core system integrates a high-power laser transmitter, wireless optical delivery subsystem, an advanced optical harvesting unit and electrical power conditioning and energy storage system. Receivers employ maximum power point tracking (MPPT) to optimize beam collection, ensure uniform photovoltaic (PV) cell illumination, and maximize electrical energy extraction. System performance is evaluated via radiative transfer modeling, with the optical delivery characterized across wavelengths under diverse atmospheric conditions. Computer simulations compare novel various materials and tandem PV cells to identify optimal configurations. Key deployment challenges include high component costs and turbulence-induced efficiency losses. Future research priorities encompass high-performance materials, component miniaturization, and robust international safety standards.
