摘要
The powersphere is an energy reception device in a laser wireless power transmission system, converting light into electricity, and also has a certain effect of light uniformity. However, in the actual application process, limitations due to laser power, photovoltaic cell absorption rate, and direct irradiation area restrict light uniformity, thus reducing photoelectric conversion efficiency. A spherical reflector at the center of the powersphere to enhance internal reflection and improve light uniformity was proposed. Utilizing LightTools software, we established a simulation model to simulate the energy distribution of light on the powersphere after reflection by the sphere, analyzing light uniformity and constructing an experimental platform for validation. Results show the reflector significantly boosts uniformity, doubling the powersphere’s output power and reducing voltage and current disparities, thereby enhancing system conversion efficiency.
