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

Siloxane resins as hydrophobic self-cleaning layers for silicon and dye-sensitized solar cells: material and application aspects

“…The obtained results are very significant compared to that with the use of TiO 2 and TiO 2 –Ag by us previously as self-cleaning coatings for PV panels. 37 …”

“…The electrical parameters of the tested photovoltaic cells were determined using a measuring stand equipped with a solar radiation simulator of AAA class, model SS200AAA EM, manufactured by Photo Emission Tech., Inc. and an SS I–V CT-02 measurement system with software for determining the electrical parameters of the cells and the advanced analysis PV Test Solutions from Wrocław, Poland. 37 …”

“…35,36 The electrical parameters of the tested photovoltaic cells were determined using a measuring stand equipped with a solar radiation simulator of AAA class, model SS200AAA EM, manufactured by Photo Emission Tech., Inc. and an SS I-V CT-02 measurement system with soware for determining the electrical parameters of the cells and the advanced analysis PV Test Solutions from Wrocław, Poland. 37 The durability test was performed via the successive immersion of a glass substrate covered with a hydrophobic layer in a water bath for 5 min and swapping with cotton cloth. This procedure was repeated 5 times.…”

“…The obtained results are very signicant compared to that with the use of TiO 2 and TiO 2 -Ag by us previously as selfcleaning coatings for PV panels. 37 Before presenting the conclusions, organosilicon derivatives of molecular or macromolecular structures (silanes, siloxanes, polysiloxanes, silsesquioxanes and silicone resins) are a group of compounds commonly applied as additives or precursors of formulations for the surface modication of various substrates. In this case, the choice of silicone resins as precursors of coating materials for the modication of the surface of photovoltaic panels and their chemical composition was dictated by both economic and technical considerations (the properties of the resins themselves).…”

TiO2-PDMS Super Hydrophilic Coating with Self-Cleaning and Antimicrobial Properties

“…Work on the combination of two materials has been reported that TiO2 -PDMS provided hydrophobic to superhydrophobic coating with good photocatalytic activity in the decomposition of methylene blue around 70%, rhodamine B 95% with water contact angle above 80-162° [13,14,15]. Other research reported combining both materials with other components such as Ag [16] and Si [11] also reported hydrophobic coating with fair photocatalytic activity. In such a manner, the correlation between their wettability and self-cleaning properties as well as antimicrobial properties TiO2 -PDMS with starch as additional binder needs further investigation.…”
