本研究的目的是确定由于水蒸气的变化对两种类型的太阳能电池，纳米晶硅（nc-Si：H）和碲化镉（CdTe）的性能在全球光谱分布的变化的影响，使用光谱辐照度模型晴朗的天空SMARTS 2在一个典型的农村环境在塞蒂夫。水蒸气可以减少到达太阳能电池的阳光量，从而导致电流、填充因子、开路电压的降低。结果表明，大气中的水蒸气增加减少了3.15%的CdTe电池的短路电流，而这种减少约为2.38%的（nc-Si：H）电池。两种电池的效率随着水蒸气的增加而增加。太阳能电池工程师应该考虑这些发现，以便更好地确定这些类型太阳能电池的尺寸。
The objective of this study is to determine the effect of variations in global spectral distribution due to the variation of water vapor on the performance of two types of solar cells, nanocrystalline silicon (nc-Si:H) and cadmium telluride (CdTe) using the spectral irradiance model for clear skies SMARTS2 over a typical rural environment in Setif. Water vapor can reduce the amount of sunlight reaching a solar cell, and thereby cause a reduction in the electrical current, fill factor, open circuit voltage. The results indicate that water vapor increase in the atmosphere reduces the short circuit current of the CdTe cell by 3.15% while this reduction is about 2.38% for the (nc-Si:H) cell. The efficiency for both cells increases with increasing water vapor. These findings should be taken into consideration by solar cell engineers for better sizing of these types of solar cells.
