摘要

温度和太阳辐照度是影响光伏电池和组件能量产量的最相关参数之一。模块温度的升高会导致开路电压的显著降低和短路电流的小幅增加。在这里,我们使用一种新的工具来确定温度系数,并根据IEC 60891和IEC 61853-1在受控的室内条件下评估基于多碳硅、单碳硅、CdTe和cigs的光伏模块的额定功率。我们使用该工具来探索模块温度的不均匀性如何影响温度系数的准确性。

A New Approach to Indoor Characterization of PV Module Energy Yield Parameters
Temperature and solar irradiance are among the most relevant parameters that affect the energy yield of photovoltaic cells and modules. A rise in the module temperature leads to a significant decrease in the open circuit voltage and a small increase in the short circuit current. Here we use a new tool to determine temperature coefficients as well as to assess power rating of multi c-Si, mono c-Si, CdTe, and CIGS-based PV modules in controlled indoor conditions per IEC 60891 and IEC 61853-1. We use the tool to explore how nonuniformities in module temperature affect the accuracy of the temperature coefficients.
