Efficiency improvement of dye-sensitized solar cells based on electrodeposited TiO2 films by low temperature post-treatment

Current Trends in Materials for Dye Sensitized Solar Cells

“…The most common deposition methods are doctor blade, screen printing, spin coating and dip coating. There are many groups working on the paste formulation, in order to simplify the deposition of TiO 2 on the substrate and to avoid cracks and peeling-up from the substrate during the posterior annealing [41][42][43][44]. Ito S. et al [41] exhaustively described a screenprinting technique from commercially-available TiO 2 for the preparation of nanocrystalline films, and cell assembly, obtaining efficiencies up to 9.2%, reducing the preparation time and making the process more suitable for industrial applications.…”

“…A decrease of the free electron scattering, that enhances the electron mobility, is produced due to an increase of the structural order at the contact between two crystalline particles with respect to nanoparticles arrays. Other techniques such as electrophoretic deposition [43,44], flat-flame chemical vapor condensation [45] and sputtering have also been used.…”

Electrodeposition of arborous structure nanocrystalline SnO2 and application in flexible dye-sensitized solar cells

“…been successfully electrodeposited [19][20][21][22]. At the same time, the electrodeposited TiO 2 and ZnO films had been extensively studied in dye-sensitized solar cells.…”

“…So the electrodeposited electrode is expected to possess fine electron transport properties even without high temperature sintering. Wessels [20] and Karuppuchamy [25] investigated the photoelectric properties of the TiO 2 and ZnO, respectively, which were used as photoanode without calcination.…”

Influence of sintering temperature on energy conversion efficiency in dye-sensitized solar cell

“…A nano-TiO 2 film, used as electron collecting and transporting component in a dye-sensitized solar cell (DSSC), is of importance to photovoltaic performance. A lot of research for improving the performance of the nano-TiO 2 film has been done [3][4][5][6][7][8][9][10] . For example, TiO 2 materials with different morphologies, such as nanoparticles [2,10] , nanotubes [11][12] , nanowires [13] , and nanofibers [14] , have been applied to fabricate the porous film electrodes.…”
