Abstract
Hydrophobic coatings have emerged as an indispensable element in enhancing the efficiency and durability of photovoltaic systems, bringing a critical advancement to energy harvesting technologies. This work realizes stable hydrophobic erbium (III) oxide (Er₂O₃) coatings using surface topography engineering. The controlled growth of the films was achieved using aerosol assisted chemical vapor deposition (AACVD) from air stable Er (III) β-diketonate complex. AACVD produced hydrophobic Er₂O₃ films exhibiting water contact angles above 90°, with the highest reaching 98°. The fundamental principles underlying water repelling properties of the Er₂O₃ films were assessed in detail via comprehensive physico-chemical characterization. The best performing films maintained water contact angle stability and were resistant to its alteration induced by surface topography which has been shown through time dependent study. This work demonstrates evidence of an intrinsic hydrophobicity of the Er₂O₃ coatings and their long-time stability.
