摘　　要：激光无线能量传输能够为各类平台提供能量补给,维持设备运行。激光电池是激光无线传能系统中的核心组件,为了研究大功率GaAs激光电池的输出特性,设计了大功率激光电池,并仿真分析了不同激光功率密度、温度等对激光电池电压、电流和转换效率的关系。实验和仿真结果都表明激光电池在100 mW/cm^(2)激光功率密度下,激光电池转换效率最高可达46.6%。并对高功率激光光束进行了匀化设计,仿真计算结果表明激光光束工作面最高功率密度可达3000 mW/cm^(2),不均匀度小于9.1%。研究首次采用单片式结构实现大功率光电转换,研究结果为大功率激光电池工程化研制奠定基础。Laser wireless energy transmission can provide energy supply for various platforms and maintain equipment operation.In order to study the output characteristics of high-power GaAs cell,a high-power photovoltaic cell was designed.The voltage,current and conversion efficiency of photovoltaic cell with different laser power density and temperature was simulated and analyzed.The experimental and simulation results show that the conversion efficiency of the laser cell is up to 46.6%at 100 mW/cm^(2) laser power density.The simulation results show that the maximum power density of laser beam working face can reach 3000 mW/cm^(2),and the nonuniformity is less than 9.1%.The research uses a monolithic structure to achieve high-power photoelectric conversion for the first time.The research results lay a foundation for the engineering development of high-power photovoltaic cell.
