由于在飞行过程中,温度、辐照度和倾角变化都会对临近空间飞行器上太阳电池的输出功率及效率产生影响,该文利用太阳光模拟器及薄型晶体硅太阳电池,进行多组测量实验,得到在不同温度、辐照度和倾角条件下,太阳电池的短路电流、开路电压等参数,并通过与模型仿真结果进行对比,对已有太阳电池电模型进行修正,得到更接近真实飞行工况的临近空间飞行器用薄型晶体硅太阳电池的模型。最后,基于修正后的模型通过仿真对太阳电池阵列在临近空间的全天发电功率变化趋势进行预测,可为临近空间飞行器用太阳电池阵列设计与功率预测提供重要参考。
Abstract
Since the changes of temperature, irradiance and inclination will affect the output power and efficiency of the solar cells on the aircraft during the flight, this article uses a solar simulator and standard thin crystalline silicon solar cells to conduct multiple sets of experimental measurements. Under different temperature, irradiance and inclination conditions, the short-circuit current, open circuit voltage and other parameters of the thin crystalline silicon solar cell are obtained, and compared with the simulation results through the model, the existing solar cell electrical model is corrected to get closer Model of thin crystalline silicon solar cell for stratospheric aircraft under real flight conditions. Finally, based on the revised model, the trend of all-day power generation of solar cell arrays in adjacent space is predicted through simulation, which provides an important reference for the design and power prediction of solar cell arrays for near space vehicles.
