III-V聚光光伏系统通过使用串联连接的多结太阳能电池获得高效率。由于这些太阳能电池在太阳光谱上的不同波段上吸收，因此它们对真实的照明条件的响应比常规硅太阳能电池更复杂。假设固定参考光谱的年度能源产量的估计值可能会因所做的假设而变化高达15%。使用详细的计算机模拟，以5分钟的间隔模拟了20单元InGaP/In0.01GaAs/Ge多结聚光器系统在一整年中的行为，考虑了直接法向辐照度，湿度，温度和气溶胶光学厚度的变化。将模拟结果与同期的选矿厂系统监测数据进行了比较，并获得了年发电量的良好一致性（在2%以内）。空气质量、气溶胶光学厚度和可降水量已被确定为对系统效率影响最大的大气参数。版权所有© 2012约翰威利父子有限公司.
III–V concentrator photovoltaic systems attain high efficiency through the use of series connected multi‐junction solar cells. As these solar cells absorb over distinct bands over the solar spectrum, they have a more complex response to real illumination conditions than conventional silicon solar cells. Estimates for annual energy yield made assuming fixed reference spectra can vary by up to 15% depending on the assumptions made. Using a detailed computer simulation, the behaviour of a 20‐cell InGaP/In0.01GaAs/Ge multi‐junction concentrator system was simulated in 5‐min intervals over an entire year, accounting for changes in direct normal irradiance, humidity, temperature and aerosol optical depth. The simulation was compared with concentrator system monitoring data taken over the same period and excellent agreement (within 2%) in the annual energy yield was obtained. Air mass, aerosol optical depth and precipitable water have been identified as atmospheric parameters with the largest impact on system efficiency. Copyright © 2012 John Wiley & Sons, Ltd.
