Abstract
En 中文
To address the problems such as small measurement area, low damage threshold, and easy saturation of existing measurement methods in laser wireless power transfer technology, this paper proposes a photovoltaic array measurement method based on current inversion, which uses the photovoltaic array composed of discrete photovoltaic cells to receive laser, and inverts the incident light intensity of the photovoltaic cell based on the mathematical model of the photovoltaic cell and the output current. Based on the output characteristic of the photovoltaic cell and the five-parameter model, the correlation model between light intensity and output current is constructed, and the accuracy of the inversion method is verified through simulation calculations under different light intensities. Light intensities obtained from the inversion are processed using cubic spline interpolation to recover the incident spot, and the total power and uniformity of the large spot are obtained based on the light intensity distribution of the light spot. The theoretical calculations and helpful for the optimal design of the laser transmitter and receiver, and also provides a theoretical basis for the development
