摘要：

A practical investigation carried out at outdoor conditions in Baghdad-Iraq winter months to evaluate the effect of traffic air pollu-tion resulted from highways on the PV cells performance. I-V characteristics, cells' power, and efficiency assessed for three cells. The re-sults indicate that the air pollution may deteriorate the PV cell performance, even with a short period of two months of the cells' outdoor ex-posure without cleaning. Also, the polluted PV cells' power reduced to about 12% while the naturally cleaned cell lost about 8% compared to the clean cell. The assaying of collected pollutants revealed high rates of hydrocarbon particulate matters resulted from traffic exhausts. PV cells' cleaning methods results indicated that using sodium surfactant as well as alcohol preserves its performance with high rates. In the same time using portable or de-ionized distilled water reduced PV cell's performance by about 14% after six weeks exposure period. The study results show that a high satisfactory possibility for using PV modules in Iraq instead of diesel or gasoline generators.
