Aerosol deposition is highly concerned recently due to its significant impact on surface glass cleaning, glass transmittance and energy conversion of building-integrated photovoltaics (BIPV). Thus, this paper reviewed direct transmittance degradation works of PV module surface glasses, and employed several integrated and improved experiment and model methods to investigate the correlation effects of PM2.5 deposition dynamics, tilt angles, surface conditions and self-cleaning TiO₂ nanocoating on glasses. Series of physical models from ambient aerosol concentration to deposition density and transmittance reduction were extended or newly developed. Measured and modeled data could inter-validate with each other and literature results. The usage condition of Al-Hasan model was discovered as $0<a_p<0.10$ for particle projected-area fraction under clustering particle projected-area fraction $a_{pcp}\le 5\%$. Ranging from 0 to 18.7 μg/cm², deposition densities with the most reductions (50–91%) were found under the combination of wet and nanocoating conditions due to effects of water film and low adhesive force. Generally, the average deposition densities decreased 19–47% with the increase of each 30° tilt angle for different surface properties. Finally, six linear empirical models were obtained with decreasing slopes of 0.001544–0.001841 between fine aerosol deposition density and transmittance ratio. These observed phenomena and derived models would be useful for solar energy, building illumination or heat-transfer, and BIPV industries.

由于气雾沉积对表面玻璃清洁，玻璃透射率和建筑集成光伏（BIPV）的能量转换有重大影响，因此近来备受关注。因此，本文回顾了光伏组件表面玻璃的直接透射降解性能，并采用了几种综合和改进的实验和模型方法，研究了PM2.5沉积动力学，倾斜角，表面条件和自清洁TiO ₂纳米涂层在玻璃上的相关影响。眼镜。从环境气溶胶浓度到沉积密度和透射率降低的一系列物理模型得到了扩展或新开发。测量和建模的数据可以相互验证，也可以进行文献验证。发现Al-Hasan模型的使用条件为$0<{\mathrm{一个}}_p<0.10$ 聚类的粒子投影面积分数下的粒子投影面积分数 ${\mathrm{一个}}_{pCp}\le 5％$。从0到18.7μg  / cm ²不等，由于水膜的影响和低粘附力，在湿法和纳米涂覆条件下，沉积密度降低最多（50-91％）。通常，对于不同的表面特性，平均沉积密度会随着每个30°倾斜角的增加而降低19–47％。最后，获得了六个线性经验模型，细小气溶胶沉积密度与透射比之间的斜率减小了0.001544-0.001841。这些观察到的现象和推导的模型将对太阳能，建筑照明或热传递以及BIPV行业有用。
