Abstract

The invention discloses a device and method for receiving and converting laser light into electrical energy output, which includes an optical component, a photoelectric conversion component and a measurement and control component, wherein the measurement and control component includes a measurement component and a control component, and the measurement and control component can control the bearing platform to adjust the posture, measure and control The components and optics are housed in a three-way housing. The invention adopts hollow spheres to construct laser multiple reflection conditions, inlays 2N pieces of special-shaped photovoltaic cells on the inner surface of the spherical cavity according to certain rules, and utilizes the multiple reflection effect of the spherical cavity to convert the received laser energy into electrical energy to the maximum extent, and can Realize the continuous and stable reception and high-efficiency conversion of the laser, and have the functions of automatic alignment and tracking of the laser beam. Aircraft pods carry airflow heat dissipation, ships submersible towing use water flow heat dissipation and other applications.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a device and method for receiving and converting laser light into electric energy output. Background technique [0002] At present, wireless charging technology originates from wireless power transmission technology, and can be divided into two methods: low-power wireless charging and high-power wireless charging. Low-power wireless charging often adopts electromagnetic induction, such as the Qi method for charging mobile phones. High-power wireless charging often adopts the resonant type (most electric vehicle charging uses this method), and the power supply equipment (charger) transmits energy to the power-consuming device, and the device enables the received energy to charge the battery and simultaneously supply it. for its own operation. Since energy is transmitted between the charger and the power-consuming device by a magnetic field, the two are not c...
