A composite material, TiO2 nanotube arrays/ZnS nanoparticles (TNT/ZnS NPs) was assembled by deposition of ZnS nanoparticles onto anodized TiO2 nanotube by sequential chemical bath deposition method. The tube-based photoanodes are crystallized at 550 ºC prior to solar cell construction. The effect of annealing of TiO2 nanotube films at 550 ºC and pH values (7.5, 8.5 9.5) of prepared ZnS nanoparticles on the photovoltaic performance of flexible solar cells is studied. The characteristics of the flexible dye-sensitized solar cell were examined using a polyaniline as a counter electrode and KI/I2 as an electrolyte. Ruthenium dye (N719) was used as an active layer. The characterizations of the films were also accomplished by using atomic force microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffractometry and FTIR. The flexible dye-sensitized solar cells of TNT/ZnS nanoparticles photoanode achieved a power conversion efficiency of 0.75 % under 80 mW/cm 2 illuminations, which is higher than that of bare TiO2 nanotube photoanode (0.3 %).

“…Dye‐sensitized solar cells (DSSCs), pioneered by Grätzel and co‐workers, have attracted sustained attention due to their potential in low‐cost solar‐to‐electricity conversion, outstanding performance under indoor conditions with low‐intensity light, great flexibility, and relatively minimal environmental issues . In DSSCs, the sensitizer is a critical component in light harvesting and electron injection and thereby influences the performance of solar cell, as well as the stability of the cells . Initial forms of this technology employed ruthenium‐based dyes, which showed over 12.0 % power conversion efficiency (PCE) .…”

A metal-free organic sensitizer, suitable for the application in dye-sensitized solar cells (DSSCs), has been designed, synthesized and characterized both experimentally and theoretically. The structure of the novel donor-acceptor-π-bridge-acceptor (D-A-π-A) dye incorporates a triphenylamine (TPA) segment and 4-(benzo[c][1,2,5]thiadiazol-4-ylethynyl)benzoic acid (BTEBA). The triphenylamine unit is widely used as an electron donor for photosensitizers, owing to its nonplanar molecular configuration and excellent electron-donating capability, whereas 4-(benzo[c][1,2,5]thiadiazol-4-ylethynyl)benzoic acid is used as an electron acceptor unit. The influences of I /I , [Co(bpy) ] and [Cu(tmby) ] (tmby=4,4',6,6'-tetramethyl-2,2'-bipyridine) as redox electrolytes on the DSSC device performance were also investigated. The maximal monochromatic incident photon-to-current conversion efficiency (IPCE) reached 81 % and the solar light to electrical energy conversion efficiency of devices with [Cu(tmby) ] reached 7.15 %. The devices with [Co(bpy) ] and I /I electrolytes gave efficiencies of 5.22 % and 6.14 %, respectively. The lowest device performance with a [Co(bpy) ] -based electrolyte is attributed to increased charge recombination.

Soft‐template synthesis of high surface area mesoporous titanium dioxide for dye‐sensitized solar cells

et al. 2018

Summary In the present work, 10 to 14 nm titania nanoparticles with high‐packing density are synthesized by the soft‐template method using a range of cationic surfactants including cetyl trimethylammonium bromide (CTAB), Sodium dodecyl sulfate (SDS), and dodecyl trimethylammonium bromide (DTAB). The synthesized nanoparticles are used as a photoanode material in dye solar cells. Density functional theory (DFT) simulations reproduce our experimental results of charge transfer and strong interaction between the TiO2 and N719. N719‐TiO2 complex establishes strong electrostatic bonding through H of the dye with the O of TiO2 surface. Solar cell efficiency of 6.08% with 12.63 mA/cm2, 793 mV, and 48.5% for short circuit current density, open circuit voltage, and fill factor, respectively, are obtained under 1 sun illumination for the dye‐sensitized solar cell (DSSC) using a film of mesoporous TiO2 synthesized from the SDS surfactant. On the other hand, the 21 nm commercial TiO2 powder (P25) device results in 4.60% efficiency under similar conditions. Electrochemical impedance spectroscopic studies show that the SDS device has lesser charge transport resistance than the other devices because of its higher surface area, packing density, and dye loading capacity. Our results show that employing high packing density‐based TiO2 nanoparticles represents a commercially viable approach for highly beneficial photoanode development for future DSSC applications.
