Effect of Alumina as an Anti-Soiling Nanomaterial
The application of an alumina nanomaterial-based anti-soiling coating on the glass substrates using the spin coating technique
In brief, fabricated porous interconnected network of aluminium oxide nanoflakes holds a great promise as cover glass for solar panels with anti-reflective and self-cleaning superhydrophobic characteristics. 4. Conclusions
Mixing of alumina with other substances, such as e.g. CaO or SiO 2, substantially facilitates the formation of the glassy phase [15, 16]. According to Hashimoto et al. pure alumina is not a glass former in melt-quenching . CaO or SiO 2, substantially facilitates the formation of the glassy phase [15,16].
Further, the prepared coating with average optical transmittance and self-cleaning superhydrophobic nature recovered the efficiency of the dust contaminated solar cell by more than 90% after being cleaned with water. These results suggested that the fabricated coating will be effectively used for self-cleaning solar panel cover glass applications.
Among them, alumina has shown promising characteristics of least toxicity, low cost, high thermal and mechanical stability. Moreover, aluminium oxide coating provides protection against abrasion by wind-borne particles and is optically transparent in the visible wavelength regions, , .
