Dye-sensitized solar cells (DSSCs) have attracted extensive attention owning to their simple preparation prcess, low cost, and relatively high energy conversion efficiency. At present, most researches are focused on TiO2-based DSSC and high powder conversion efficiency of over 12.3% has been obtained. As a potential candidate, Zn2SnO4has drawn increasing attention for DSSCs due to its attractive electrical and optical properties (Eg = 3.6 eV, electron mobility of 10–15 cm2V-1s-1). In this article, we maily reviewed the recent progress of Zn2SnO4-based DSSCs and put forward ideas for designing new Zn2SnO4materials in future application for DSSCs.

Dye-sensitized solar cells (DSSCs) have been widely studied due to several advantages, such as low cost-to-performance ratio, low cost of fabrication, functionality at wide angles and low intensities of incident light, mechanical robustness, and low weight. This paper summarizes the recent progress in DSSC technology for improving efficiency, focusing on the active layer in the photoanode, with a part of the DSSC consisting of dyes and a TiO2film layer. In particular, this review highlights a huge pool of studies that report improvements in the efficiency of DSSCs using TiO2nanotubes, which exhibit better electron transport. Finally, this paper suggests opportunities for future research.

Highly oriented single-crystalline rutile TiO2 nanowires on transparent conductive fluorine-doped tin oxide (FTO) substrates are prepared by low-temperature hydrothermal method. The small lattice mismatch between FTO substrate and rutile TiO2 promote the epitaxial nucleation and growth of rutile TiO2 nanowires on FTO, with the diameter of 4–6 nm. Due to Van der waals force, the ultrafine nanowires tend to gather together, forming nanowire bundles. Using the ultrafine nanowire bundle array as the photoanode and ruthenium complex (N719) as the sensitizer, dye-sensitized solar cells (DSSCs) are assembled. The effect of the TiO2 nanowire gathering on the power conversion of the DSSCs has been investigated. Experimental result shows that the light-to-electricity conversion efficiency is increased by reducing the gathering of the nanowires through introducing toluene into reactant precursors. The DSSCs based on the bundles with smallest average width (i.e., least nanowire gathering) show the highest power conversion efficiency of 3.70%. The relatively high energy conversion efficiency is contributed to the large surface area, which enhances the adsorption of dye molecules.

One-dimensional nanostructured semiconductor oxides that can provide a direct electron conduction pathway have received increasing attention as photoelectrodes in dye-sensitized solar cells. In this study, a facile and cost-effective method to produce high-quality TiO2 nanofibres is developed based on an electrospinning technique. In particular, poly(ethylene oxide) was selected and proved to be an excellent matrix polymer for electrospinning owing to its low decomposition temperature, wide availability, and environmental friendliness. In addition to obtaining TiO2 nanofibres with well-controlled morphology and pure anatase, the TiO2 grain size could be easily tuned by changing the preparation conditions. Based on the synthesized TiO2 nanofibres, dye-sensitized solar cells were fabricated and a high energy conversion efficiency of 6.44 % was achieved under illumination with air mass 1.5 (100 mW cm–2) simulated sunlight, which demonstrates the great potential of the synthesized TiO2 nanofibres as efficient photoelectrode material for low-cost dye-sensitized solar cells.

Dye-sensitized solar cells (DSSCs) based on a TiO2photoanode have been considered as an alternative source in the field of renewable energy resources. In DSSCs, photoanode plays a key role to achieve excellent photo-to-electric conversion efficiency. The surface morphology, surface area, TiO2crystal phase, and the dispersion of TiO2nanoparticles are the most important factors influencing the properties of a photoanode. The smooth TiO2surface morphology of the photoanode indicates closely packed arrangement of TiO2particles which enhance the light harvesting efficiency of the cell. In this paper, a smooth TiO2photoanode has been successfully prepared using a well-dispersed anatase TiO2nanosolviaa simple hydrothermal process. The above TiO2photoanode was then compared with the photoanode made from commercial TiO2nanoparticle pastes. The morphological and structural analyses of both the aforementioned photoanodes were comprehensively characterized by scanning electron microscopy and X-ray diffraction analysis. The DSSC fabricated by using a-TiO2nanosol-based photoelectrode exhibited an overall light conversion efficiency of 7.20% and a short-circuit current density of 13.34 mA cm−2, which was significantly higher than those of the DSSCs with the TiO2nanoparticles-based electrodes.
