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.

Zinc oxide (ZnO) and Ag deposited ZnO (ZnO@Ag) core-shell nanorods produced electrochemically on indium tin oxide coated glass (ITO) substrate for the first time without any organic surfactants or high annealing temperature. Nanorod films were synthesized two-step synthesis procedure. Firstly, ZnO nanorods electrodeposited at low temperature, in second step, in situ electrochemically etching of deposited ZnO nanorod was carried out. Characterizations of electrochemically produced films have been carried by using morphologic, spectroscopic and structural analysis methods by using X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscope (AFM), fourier transform infrared spectroscopy (FTIR), Elemental mapping, UV-visible diffuse absorption spectra and photoluminesance spectroscopy (PL). The photocatalytic performance of the obtained films was determined by degradation of methylene blue and malachite green dyes under UV light illumination. Methylene blue and malachite green dyes completely degraded under UV light irradiation after 150 and 180 min, respectively. Also, photoelectrochemical (PEC; water splitting) performances of the produced films were investigated under dark conditions and UV light irradiation. The ZnO@Ag core-shell nanorods exhibited higher photocatalytic and photoelectrochemical performance in comparison with unmodified ZnO nanorods film. The nanorods grown on the ITO substrates showed very good photocatalytic activity and became reusable without significant loss of activity.

“…Another advantage of DSSCs in comparison to other solar cell technologies is the better utilization of diffuse or low-intensity illumination. As unique characteristics, DSSCs are semi-transparent, if both electrodes are based on transparent substrate materials, and their color can be varied [ 2 , 3 ]. The semi-transparency permits a versatile optical design of the solar cells.…”

The low-temperature fabrication of flexible ZnO photo-anodes for dye-sensitized solar cells (DSSCs) by templated electrochemical deposition of films was performed in an enlarged and technical simplified deposition setup to demonstrate the feasibility of the scale-up of the deposition process. After extraction of eosin Y (EY) from the initially deposited ZnO/EY hybrid films, mesoporous ZnO films with an area of about 40 cm2 were reproducibly obtained on fluorine doped tin oxide (FTO)-glass as well as flexible indium tin oxide (ITO)–polyethylenterephthalate (PET) substrates. With a film thickness of up to 9 µm and a high specific surface area of up to about 77 m2·cm−3 the ZnO films on the flexible substrates show suitable properties for DSSCs. Operative flexible DSSC modules proved the suitability of the ZnO films for use as DSSC photo-anodes. Under a low light intensity of about 0.007 sun these modules achieved decent performance parameters with conversion efficiencies of up to 2.58%. With rising light intensity the performance parameters deteriorated, leading to conversion efficiencies below 1% at light intensities above 0.5 sun. The poor performance of the modules under high light intensities can be attributed to their high series resistances.
