Optical field manipulation for highly efficient wireless laser power transmission
2020 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2020We investigate the influence of laser incident at different angles on the output characteristics of PV cells. Meanwhile an inverse design method is proposed that generates optical field from the geometry of photovoltaic (PV) cells by using a spatial light modulator (SLM).
