中文摘要:光伏组件在运行过程中, 受遮蔽物遮挡产生阴影时会引发光伏电池阴影效应, 导致电池片输出性能明显的变 化, 而光伏串联模组中存在的失配现象为光伏阴影效应的主要成因。研究了阴影面积、阴影分布两个方面对由光伏 失配导致的光伏电池阴影效应。结果表明, 阴影面积、阴影分布是影响阴影条件下光伏电池性能的重要因素。运用 光伏等效电路模型, 对光伏电池阴影效应的成因进行了相关电路分析。

Effect of Crystallization Time and Mother Liquor Recycling onthe Synthesis of SAPO-34 Molecular Sieve
Abstract:During the operation of photovoltaic modules, the shadow effect of photovoltaic cells takes place when they are shaded by the shelter, which leads to obvious changes in the output performance of the cells. The photovoltaic mismatch phenomenon in the photovoltaic series modules is the main cause of the photovoltaic shadow effect. The shadow effect of photovoltaic cells caused by photovoltaic mismatch has been investigated from two aspects including shadow area and shadow distribution. It is indicated that the shadow area and shadow distribution are important factors affecting the performance of photovoltaic cells under shadow conditions. By using the photovoltaic equivalent circuit model, the causes of the shadow effect of photovoltaic cells have been further analyzed.
