摘要:

本文构建了一种分布式激光输能系统,该系统采用半导体激光器发射激光,经透镜调节后,照射到远处的太阳能电池上转换为直流电能。利用该系统,实验研究了在发射端与接收端距离10 m的情况下,三种波长的激光单独输能及相同和不同波长激光混合输能时的系统的光电能量转换效率,并对150 m输能距离的激光输能进行了初步实验探索。同时本文研究分析了该系统的设计和激光在传输过程中的功率损耗等问题。

In the paper, a kind of distributed laser-powered system is constructed. The system can transmit power with laser beam directed to the photovoltaic cells by the beam-steering lens from the semiconductor laser. At the distance of 10 m between the emitter and receiver, the light-electricity transmission efficiency is studied by experiments with this system in the different situations, using single wavelength or different wavelength laser of three kinds to transmit power, and a preliminary exploration is implemented for the wireless energy transmission at the distance of 150 m. At the same time, the design of the system and the energy consumption are analyzed.
