Abstract
In the frame of this project the basic knowledge for the exploitation of unconventional sources of energy will be gathered in order to promote their development and use in Slovenia. The main goal is to develop the gel (semi-solid) electrolytes which are appropriate for the fabrication of dye-sensitized photoelectrochemical (DS PEC) cells considered as energy active devices and self-erasing electrochromic (EC) devices considered as energy passive devices. Electrolytes will be synthesized from organic-inorganic hybrids containing end-capped-triethoxy silane groups covalently bonded via either urea- or urethane-groups to the polypropylenglycol (PPG), polyethyleneglycole (PEG) or block PPG/PEO/PPG chains of different lengths. Together they will form hosts in which co-solvents with high boiling points (cca 200 degrees C) will be embedded. Cross-linking of the hybrid/co-solvent mixtures will be performed using various acid catalysts, for example aliphatic organic acids, polyethylenglycol 600 diacid and other water-free catalysts. The formed lyogels will be extensively tested for the fabrication of DS PEC and EC devices and their efficiency and stability will be established. In addition, various thin oxide films with ion-storage characteristics for the use in both kinds of cells will be synthesized and their functioning will be tested in the devices.
