Deposition methods of TiO2 on the glass and characterisation of conductive layer in DSSC DOI:10.15199/13.2018.9.2

  The use of renewable energy sources is currently one of the greatest challenges for humanity [1 - 4]. Dye - sensitized solar cells (DSSCs) constitute a group of cells in which the process of converting solar energy directly into electricity takes place [5 - 7]. The construction of these cells is based on semiconductor materials (including TiO2) sensitized with organic dyes to increase the range of electromagnetic radiation absorption [2, 8 - 10]. An important parameter is the specific surface of the semiconductor, which determines the degree of dye adsorption [1, 11, 12]. In DSSC, TiO2 layer functions as nanoparticles with anatase crystal structure, thanks to which the active surface of light absorption is much higher. Nanopores TiO2 layers on the surface of the glass substrate are deposited, e.g. by screen printing [13], sol - gel [14, 15], sputtering [16] and doctor blade techniques. When it comes to the advantages of DSSC, the biggest one is undoubtedly a slight reduction of efficiency in low light and the ability to work at a wide angle of radiation. It is possible to extend the applications of this type of cells by modeling their shape and using different colors of dye in the production [4]. What’s more, thanks to the sandwich construction of DSSC cells, in which the outer coating is made of glass, the panel is resistant to changing weather conditions and mechanical damage [17]. Experimental The DSSC test cells were prepared as follows: glass plates with a TCO layer (SnO2: F) with the thickness 3,2 mm and a resistivity about 10 Ohm/ cm2 were subjected to a laser-str[...]
