“…In the current work, cells made with an optimum thickness of 15 m exhibited a J sc of 10.1 mA/cm 2 , V oc of 0.64 V, a fill factor (ff) of 0.65, and a light power conversion efficiency () of ~ 4.3 %. The conversion efficiency is comparable to those reported earlier for analogous cells fabricated with commercial TiO 2 powders (P25) using traditional techniques (Okuya, 2002;Nakada, 2002;Hinsch, 2001). …”

“…The porous TiO 2 thin film can be fabricated by spray pyrolysis technique as well [51]. Spray pyrolysis is a version of spray coating but needs a higher substrate temperature to assure the occurrence of the chemical decomposition of the liquid precursor needed to form a ceramic thin film plus some volatile gases.…”

“…Spray pyrolysis is a version of spray coating but needs a higher substrate temperature to assure the occurrence of the chemical decomposition of the liquid precursor needed to form a ceramic thin film plus some volatile gases. Titanium (IV)oxy acetylacetonate 2-butanol solution may be used as the starting precursor for the fabrication of TiO 2 thin films with a substrate temperature of about 300 °C [51]. Also, Nb 2 O 5 produced by spray pyrolysis may be used as the counter electrode in a DSSC [52].…”

Abstract:The capability to fabricate photovoltaic (PV) solar cells on a large scale and at a competitive price is a milestone waiting to be achieved. Currently, such a fabrication method is lacking because the effective methods are either difficult to scale up or expensive due to the necessity for fabrication in a vacuum environment. Nevertheless, for a class of thin film solar cells, in which the solar cell materials can be processed in a solution, up scalable and vacuum-free fabrication techniques can be envisioned. In this context, all or some layers of polymer, dye-sensitized, quantum dot, and copper indium gallium selenide thin film solar cells illustrate some examples that may be processed in solution. The solution-processed materials may be transferred to the substrate by atomizing the solution and carrying the spray droplets to the substrate, a process that will form a thin film after evaporation of the solvent. Spray coating is performed at atmospheric pressure using low cost equipment with a roll-to-roll process capability, making it an attractive fabrication technique, provided that fairly uniform layers with high charge carrier separation and transport capability can be made. In this paper, the feasibility, the recent advances and challenges of fabricating spray-on thin film solar cells, the dynamics of spray and droplet impaction on the substrate, the photo-induced electron transfer in spray-on solar cells, the challenges on characterization and simulation, and the commercialization status of spray-on solar cells are discussed.

“…[10], and no much effort has been made in the published literature related to effect of multiple reaction parameters and durability and mechanical strength of obtained photocatalyticinfrastructure materials [22]. Titania coatings are generally layers of around 200 nm of thickness [23], which are deposited using some techniques, such as sputtering [24], electrophoretic deposition [25], spray pyrolysis [26], thermal oxidation [27], chemical vapor deposition [28] and wet coating [29], among the main reported methodologies.…”

a b s t r a c tAn increasingly known application of nanomaterials in the construction industry is related to the photoactivity ability of semiconductors, where nano-anatase TiO 2 is perhaps the most well-known photocatalytic semiconductor and one which possesses a strong oxidizing capability. To analyze the photo-efficiency of four TiO 2 coatings and the effect of SiO 2 interlayer on the mechanic and photocatalytic activity in Rhodamine B (RhB) and NO x photodegradation, two photocatalytic cement series have been prepared. First, cement mortar was coated with three commercial TiO 2 suspensions (GG1, GC7 and CG13) and a home-made titania sol-gel (TEA), and secondly an insertion of a SiO 2 layer was applied on cement surface before spraying the TiO 2 layer.All studied TiO 2 -cements exhibited a significant RhB and NO x photodegradation, arising almost total RhB molar conversions, and upper 53% for NO x photo-oxidation respectively. Nevertheless, although SiO 2 layer deposited in between mortar and TiO 2 -cement did not stabilize the commercial TiO 2 coatings, a good adhesion was observed when silica was applied joint to the home-made titania gel (TEA), probably as a consequence of the interactions encountered between SiO 2 and TiO 2 gels. CG7-Si-Cem exhibited high rate at shorter irradiation times, but TEA-Cem and TEA-Si-Cem can be considered as very interesting and potential photocatalytic mortars due to useful mechanical properties, with a very good coatings adhesion that provides promising outdoor use, and good photo-efficiencies in RhB and NO x photo-oxidation.
