“…209 Besides TiO 2 , ZnO has also been regarded as a promising photoanode candidate for use in dye-sensitized solar cells. [210][211][212] Tian et al tested the performance of multishelled ZnO hollow microspheres for this purpose, which was obtained by the hydrothermal treatment of a zinc gluconate solution with the desired acidity followed by a calcination treatment. 44 Cells based on multishelled ZnO hollow microspheres deliver a higher current density of 13.04 mA cm À2 with conversion efficiency of 4.13%, which is much better than the cells based on commercial ZnO solid spheres.…”

“…Attempts have been made to study quasi-solid electrolyte, for instance, Chen In terms of redox couple, iodide-based redox couple (I − /I − ) is most frequently employed as mediator in FDSSCs, but its corrosion effect, intense visible light absorption and low redox potential push researchers to look for replaceable redox [55,80]. Given no variation between flexible and rigid DSSCs in operational principle, the redox couples employed in rigid DSSCs, such as cobalt-based redox couple (Co 2+ /Co 3+ ), vanadium redox couple (V 2+ /V 3+ ), organic sulfide redox couple (T 2 /T − ) and copper-based redox couple (Cu + /Cu 2+ ) all can be introduced directly into FDSSCs [155][156][157][158].…”

With growing demand for economic, eco-friendly, easy-manufacturing and renewable portable power source, flexible dye-sensitized solar cells (FDSSCs) exhibit a promising potential in the field of portable power sources. However, FDSSCs surfer from low conversion efficiency and poor stability, which hinder their applications. In this work, we have summarized recent development and challenges according to respective functions of their vital components (substrate, semiconductor film, sensitizer, electrolytes and counter electrode) as well as their effects on photoelectric conversion efficiency. Meanwhile, typical fabrication approaches have been analyzed for increasing the incident photon to current efficiency (IPCE). The approaches in rigid dye-sensitized solar cells (DSSCs) for improving performance are also introduced to provide the favorable direction for accelerating FDSSCs' application in field of potable power source.

“…The typical semiconductor metal oxide used is TiO 2 , in its anatase crystalline form, which is the same employed in the pioneering work of O'Regan and Grätzel ( 1991 ). Interestingly, despite a huge research effort in the search for alternative semiconductor materials such as ZnO (Anta et al, 2012 ; Canto-Aguilar et al, 2017 ; Vittal and Ho, 2017 ) and SnO 2 (Pari et al, 2013 ; Li et al, 2014 ), TiO 2 still remains the material that provides the best efficiency in photovoltaic devices (Bai et al, 2014 ; Cavallo et al, 2017 ). It is also an abundant material characterized by well-established low-cost synthetic preparation procedures.…”

Dye sensitized solar cells (DSSC) are considered one of the most promising photovoltaic technologies as an alternative to traditional silicon-based solar cells, for their compatibility with low-cost production methods, their peculiar optical and mechanical properties and the high indoor efficiency. Photosensitizers represent one of the most important components of a DSSC device and probably the most thoroughly investigated in the last twenty years, with thousands of dyes that have been proposed and tested for this kind of application. In this review we aimed to provide an overview of the three main classes of DSSC photosensitizers, namely ruthenium(II) polypyridyl complexes, Zn-porphyrin derivatives and metal-free organic dyes. After a brief introduction about the architecture and operational principles of a DSSC and the state of the art of the other main components of this type of device, we focused our discussion on photosensitizers. We have defined the numerous requirements DSSC photosensitizers should satisfy and have provided an overview of their historical development over the years; by examining specific dyes reported in the literature, we attempted to highlight the molecular design strategies that have been established for the optimization of their performance in real devices both in terms of efficiency (which recently reaches an outstanding 14.3%) and operational stability. Finally, we discussed, in the last section, the possible future developments of this intriguing technology.
