摘要

本工作旨在评估TiO2作为光伏板自清洁层的主要层成分。研究了含银和不含银的二氧化钛(丁氧钛和异丙醇钛)的微观结构和光学性能。为此目的,银用量范围为0.1至1%,用于3种不同的化学改性方法。采用扫描电子显微镜(SEM)和透射电子显微镜(TEM)结合x射线能谱对粉末的微观结构进行了表征。采用旋转镀膜、医生刀片和喷涂三种技术在玻璃和硅太阳能电池上沉积TiO2和TiO2 - ag层。研究了TiO2和TiO2 - ag在亚甲基蓝存在下的光催化活性。分析了染料浓度、银用量、银改性TiO2的种类及随时间的稳定性对最佳光催化性能的影响。最后,用于新型光伏组件包覆的TiO2层对光伏参数的影响微乎其微。

TiO2 and TiO2–Ag powders and thin layer toward self-cleaning coatings for PV panel integrated with sound-absorbing screens: Technical approaches

This work aims at assessment of TiO2 as the main layer component for self-cleaning layers in photovoltaic panels. TiO2 (derived from titanium (IV) butoxide or titanium (IV) isopropoxide) without and with silver was examined to find titania suitable microstructure and optical properties. For this purpose silver amounts ranging from 0.1 to 1% were used for 3 separate chemical methods of modification. Microstructure of powders was characterized by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) with X-ray energy dispersion spectroscopy. Three techniques: spin-coating, doctor blade, and spray-coating were used to deposit TiO2 and TiO2–Ag layers on glass and silicon solar cells. The photocatalytic activity of TiO2 and TiO2–Ag were investigated in the presence of methylene blue. Concentration of dye, amount of silver, type of TiO2 with Ag modification and stability over time were analysed towards the best photocatalytic properties. Finally, TiO2 layers which were used to coat a new type of photovoltaic modules had marginal influence on photovoltaic parameters.
