PY - 2016/07/14/ TI - Optical Properties of Mesoporous and Nanocrystalline Titanium Dioxide Obtained Using Doctor Blade Technique JF - Revista Cubana de Física; Vol 33 No 1 (2016) KW - N2 - The optical properties of nanocrystalline and mesoporous titanium dioxide (TiO 2 ) 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 TiO 2 is discussed and the spectra are reported. The use of the obtained optical constants to find the thickness of TiO 2 films, similar to those studied, is discussed. UR - http://revistacubanadefisica.org/index.php/rcf/article/view?path=
