Plastic lens integrated III‐V compound semiconductor cell (PIC) modules or other microconcentrator/miniconcentrator photovoltaic (CPV) modules reduce the volume and weight of CPV modules to a size comparable to flat panel photovoltaics. However, the areal density of solar cells and lenses in a PIC or other micro‐mini‐CPV modules significantly increases by at least an order of magnitude, which raises the required precision and consistency of the module assembling, because a slightly misaligned solar cell can limit the current of the whole circuit and inhibit the performance of the full module. In this study, we presented the results of a 1 m² module consisting of 2025 solar cells with a direct‐normal‐irradiance efficiency of more than 30%. To the best of our knowledge, this is the largest area for a CPV module with a height of less than 5 cm reported so far. To quantify the different causes of misalignment, we proposed a probabilistic analysis to model how these errors affect the performance of the CPV module. The results show that the dominant error of the PIC module is attributed to around 0.5° misaligned orientation between the unit modules. This analysis approach can also be applied to other types of micro‐CPV modules.

将塑料集成聚光光伏面板放大至1平方米的演示和误差分析

集成了塑料透镜的III-V化合物半导体电池（PIC）模块或其他微型集中器/微型集中器光伏（CPV）模块将CPV模块的体积和重量减小到可与平板光伏相比的大小。但是，PIC或其他微型CPV模块中的太阳能电池和透镜的面密度至少显着增加了一个数量级，这提高了模块组装所需的精度和一致性，因为稍微不对准的太阳能电池会限制整个电路的电流并抑制整个模块的性能。在这项研究中，我们介绍了1  m ²该模块由2025个太阳能电池组成，其直接正常辐射效率超过30％。据我们所知，这是迄今为止报道的高度不到5厘米的CPV模块的最大面积。为了量化未对准的不同原因，我们提出了一个概率分析，以建模这些误差如何影响CPV模块的性能。结果表明，PIC模块的主要误差归因于单元模块之间约0.5°的未对准方向。这种分析方法也可以应用于其他类型的微型CPV模块。
