Abstract

The optical properties of nanocrystalline and mesoporous titanium dioxide (TiO2) layers, obtained using the “doctor blade” technique, are analyzed. These layers are used in different sensitized solar cell types, as well as, in the novel perovskite solar cells. Transmittance and diffused reflection spectra of different layers deposited on optical glass are reported and compared. Using Swanepoel method, the refractive index is determined in the 600-800 spectral range from transmittance spectra. Feasibility of obtaining the spectral dependence of an effective absorption coefficient for mesoporous TiO2 is discussed and the spectra are reported. The use of the obtained optical constants to find the thickness of TiO2 films, similar to those studied, is discussed.
