Anti‐reflection coatings have potential usage in photovoltaic solar cells, sensors, and display devices to reduce reflectance, glare and enhance light transmission. ARC was developed to increase more efficiency of solar cell cover glasses, by depositing SnO2/TEOS/MTMS coating using the sol–gel spin coating technique. The coating showed a maximum transmittance of 92.70% at 399 nm wavelength with an average refractive index of 1.42. The transmittance of the antireflective film was increased by 2.29% than the bare glass substrate. The surface morphology of the coatings was investigated using FESEM analysis. The mechanical stability of the coating was evaluated using ASTM standard D 3363–05 pencil scratch test, and it demonstrated good performance against 3H hardness pencil. The efficiency of solar cells has been increased by 1.56% after depositing with single layer SnO2/TEOS/MTMS film. Moreover, the coating maintains the solar cell's performance even during dust exposure, because of its self‐cleaning ability with water contact angle of 94°. Thus, the Anti‐reflection coating can be applied to enhance the efficiency of photovoltaic system. [ABSTRACT FROM AUTHOR]

Antireflective (AR) coatings are widely used in the various applications of optical devices, flat panel displays, automotive windshields, and solar cell cover glasses. Usually, coatings with high transmittance and self-cleaning capability enhance solar cell efficiency. In this work, SnO2 thin film with TEOS, ITES, and MTES by spin coating was deposited on glass substrates and analyzed. The prepared films was characterized by Fourier Transform Infrared Spectroscopy, UV-visible spectroscopy, FESEM, and Water contact angle measurements (WCA). The prepared SnO2/TEOS/ITES and SnO2/TEOS/MTES films showed good optical transmittance of 92.46% and 92.56% with WCA of 9° and 92° respectively. The transmittance of the antireflective films was increased by 2% than the bare glass substrate. Also, the antifogging behavior of SnO2/TEOS/ITES film was examined. Furthermore, the self-cleaning ability of the coatings helps to maintain the efficiency of the solar cell even during dust exposure. Thus, the antireflection coating can be applied to enhance the efficiency of the photovoltaic system. [ABSTRACT FROM AUTHOR]
