Comparison of the dye-sensitized solar cells performances based on transparent conductive ITO and FTO

Structural and Optical Properties of Spray Coated Carbon Hybrid Materials Applied to Transparent and Flexible Electrodes

“…In most cases transparent electrodes are fabricated with physical and chemical vapour deposition methods (PVD and VCD), which can be used for the deposition of conductive thin metal oxide layers like indium tin oxide (ITO) [10], (AZO) [11], (FTO) [12], (GZO) [13], or (ZnO) [14]. Vacuum techniques are strongly linked with many technological issues like complicated and expensive equipment and problems in providing stable quality of vacuum in larger chambers and high installation and exploitation costs.…”

Nanostructured Dye Sensitized Solar Cells

“…[7,[15][16][17][18][19]. In order to achieve sufficiently high solar energy conversion, anatase TiO2 is used in DSSCs in a nanocrystalline form, with an optimal nanoparticle diameter of about 25 nm.…”

“…Ruthenium and osmium complexes have shown the best photovoltaic performance in terms of both conversion yield and long-term stability [12][13][14][15]. In particular, these performances are achieved when these metals are coordinated with polypyridyl complexes, thanks to an overall broad absorption spectrum ( Up to now the cis-bis(isothiocyanato) bis(2,2'-bipyridil-4,4'-dicarboxilato ruthenium (II) (commonly named N3, Figure 1.9, on the left) and ditetrabutylammonium,cis-bis(isothiocyanato)bis(2,2'-bipyridil-4,4'-dicarboxilato ruthenium (II), commonly named N719 (on the right), show the best photovoltaic performances, which result to be 10.4% [24] and 11.18% [25].…”

“…Also the incident light power, which affects internal cell phenomena like charge recombination at interfaces or local heating, influences markedly the measured IPCE, varying its magnitude and even the shape of the IPCE-λ curve. Therefore, IPCE measurements on DSSCs are rather sensitive experiments, and the conditions in which they are carried out must be carefully tuned and controlled in order to obtain an IPCE determination useful for comparisons with other devices [3,[14][15].…”

“…It is worth to note that both the types of photoanodes were fabricated using two scotch tape layers as spacers for the doctor-blading tool (see showed that the A-TiOx layers had a layer density about 30% lower than that of the K-TiOx, it was decided to increase the layer thickness of about 30%, in order to obtain two layer (of the A-and K-type) with approximately the same overall number of TiOx nanoparticles. Therefore, new batches of A-TiOx layers were fabricated using three layers of scotch tape, obtaining A-TiOx layers about [15][16] microns-thick, while the K-TiOx layers were fabricated using the standard 2 layers of scotch tape, so to obtain about 11 microns-thick TiOx layers. The results of this approach are summarized in Figure 5.12 and in 5.…”
