Paper Abstract

In the laser wireless power transmission (LWPT) system, the solar panel plays a decisive role as the receiving end of the energy. As the transmission medium of energy in LWPT system, the energy of laser presents generally Gauss distribution, resulting in uneven energy of the laser received by the solar panel, which may affect the transmission efficiency and capacity of the system. In this paper, a 1070nm continuous fiber laser is used to irradiate the In0.3Ga0.7As solar panel, and the temperature distribution on the back of the panel and the IV characteristics were recorded. The results showed that the temperature distribution on the back side of the solar panel was almost the same under the conditions of the same laser power but different energy distribution. In terms of performance of the panel, due to the increase in beam uniformity, the short-circuit current increased by 33.4%, the maximum output power increased by 18.5%. In addition, the irradiation of different laser power was also studied in this paper. The influence of different laser intensity and different beam uniformity on the efficiency of the panel were given.
