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) 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.

Recently, dye-sensitized solar cells (DSSC) have concerned significant attention attributable to their material preparation process, architectural and environmental compatibility, also low cost and effective photoelectric conversion efficiency. Therefore, this study aimed to use potential plant materials for DSSC. This research presents the extraction of natural pigments from yellow cotton flowers (Cochlospermum regium). In addition, the natural pigments were revealed that outstanding advantages, including a wide absorption range (visible light), easy extraction method, safe, innocuous pigments, inexpensive, complete biodegradation and ecofriendly. Methanol was used as a solvent extraction for the yellow cotton flower. The chlorophylls and carotenoid pigments extractions were estimated by a UV-visible spectrometer. The chlorophyll-a, chlorophyll-b, and carotenoid yield were 0.719±0.061 µg/ml, 1.484±0.107 µg/ml and 7.743±0.141 µg/ml, respectively. Thus, this study results suggested that yellow cotton flowers containing reasonable amounts appealable in the DSSC production.
