摘要
设计了一种太阳能光伏发电-激光供能系统,讨论了系统中能量转换效率和供能损耗问题。实验采用人工太阳模拟发射器,通过光伏发电给半导体激光器提供能量发射红外激光,采用透镜准直后照射到光电池上转换成电能。测量了各装置的输入输出功率,计算了能量转换装置的转换效率和传输过程中的能量损耗,提出了改进系统的有效途径。
A system of the utilization of photovoltaic generation and then supply energy by laser was designed, and efficiency of energy conversion instruments and energy loss was studied. The Artificial Sun Simulating Emitter was introduced in the experiment, which was used to supply power for semiconductor laser to emit infrared laser beam, and the beam irradiates onto photovoltaic ceils to produce electric power through collimating lens. Input and output power of instruments was measured, and efficiency of energy conversion instruments and energy loss was calculated, and effective methods were put forward to improve the system.
