The red arrows in (c) and (d) correspond to the slightly elevated spots at the intersections of neighboring pores [249]. Copyright 2012 Royal Society of Chemistry. which exhibited efficient decrease of reflection toward wavelengths ranging from visible to the near infrared region at a wide range of incident angles [66]. The 2D arrays of rutile TiO2 nanorods with a unique tips-on-rod structure led to an optimized graded RI and hence prominent broadband and quasi-omnidirectional AR properties, as shown in Fig.

4 Spray-coating Spray-coating is quite a facile method, which is not specific to a particular substrate and can be easily applied to a large surface area [126]. As spray-coating does not typically require other complicated and costly processes, it is commercially feasible for a wide range of applications. The general process of spray-coating is shown in Fig. 12a. This method is simple, fast, material efficient, easy to use, carried out in non-vacuum system, and permits to obtain films with required properties for large area applications [127].

17 18 Multifunctional Coatings for Solar Energy Applications The LbL assembly technique has several advantages in the preparation of ARCs. First, as mentioned above, varied materials (building blocks) can be used to fabricate ARCs and the LbL processing is substrate-independent. Second, it is possible to deposit ARCs of large areas on non-flat surfaces by the LbL assembly technique. Third, it is easy for the LbL assembly technique to control over the film thickness, and therefore, to tailor the wavelength of maximum transmittance simply by changing the number of film deposition cycles [107,108].
