High Absorption Coefficient Cyclopentadithiophene Donor-free Dyes For Liquid and Solid-state dye-sensitized Solar Cells
No full textWe report a series of ‘donor-free’ dyes, featuring moieties of oligo(4,4-dihexyl-4H-cyclopenta[1,2-b:5,4-b’]dithiophene) (CPDT) functionalized with cyanoacrylic end groups for mesoscopic titania solar cells based on I-/I3- or Co(II)/Co(III) redox couple and spiro-OMeTAD hole transporter. These were compared with similar cells using an oligo(3-hexylthiophene) dye (5T) which we have reported before. Extending the CPDT moiety of the dye molecules from one to three (denoted as CPDT-1, CPDT-2 and CPDT-3) widens the photoresponse overlap with the solar spectrum, increases the molar absorption coefficient up to 75000 M-1cm-1 and improves the short-circuit current (JSC), open-circuit voltage (VOC) and power conversion efficiency (PCE) for all types of DSSCs. Among these sensitisers, CPDT-3 shows the highest PCE of 6.7%, 7.3% and 3.9% with I-/I3-, Co(II)/Co(III) redox couple and spiro-OMeTAD hole transporter, respectively, compared with 7.6%, 9.0% and 4.0% for 5T. Benefiting from the high absorption of CPDT-3, we demonstrate 900 nm-thick mesoporous TiO2 film with remarkable JSC of 10.9 mA cm-2 in solid-state DSCs
Sequential Ionic Layer Adsorption and Reaction (SILAR) deposition of Bi4Ti3O12 on TiO2: an enhanced and stable photocatalytic system for water purification
No full textA new method to produce bismuth titanate – titanium dioxide composites by modification of a TiO2 film deposited on a variety of different glass substrates is reported. Using a simple SILAR method, BiOBr may be deposited upon TiO2 surfaces, which upon heating forms a closely intercalated structure of bismuth titanate (Bi4Ti3O12, BTO) and TiO2. This new method expands the scope of the SILAR process, which is typically restricted to materials which can be formed from soluble precursors. This composite material has undergone a thorough materials characterisation to confirm the absence of the BiOBr precursor, and the formation of the new bismuth titanate phase. The electronic structure of the heterojunction formed has also been investigated by valence band XPS and diffuse reflectance measurements, and a plausible band structure proposed. The immobilised composites have then been applied to the photocatalytic degradation of organic pollutants and bactericidal testing, as well as stability tests and identification of the key reactive species. Further photocatalytic studies have been carried out on this material in a synthetic wastewater medium, taking a step towards application under real-world conditions
