Dye-sensitized solar cells (DSSCs) have emerged as a high-efficiency, low-cost alternative to solid-state silicon solar cells. Typically, DSSCs are composed of a mesoporous titania nanocrystal electrode on a transparent conductive oxide (TCO) substrate with ruthenium-based sensitizers on the titania nanocrystals, platinum on the TCO substrate as a counter electrode, and iodine/iodide electrolyt...

In recent years, the development of DSSC produced considerable research interest, including improving efficiency, packaging and flexible possibilities. Flexible possibility has great potential for all kinds of applications. Researches on the bendability of the solar cell thin sheets are mostly focus on the making the soft substrate or electrodes. Previous studies showed that coating method of T...

The counter electrodes (CEs) for flexible dye solar cells (DSCs) are normally prepared by sputtering platinum on indium tin oxide (ITO) plastic substrate. However both ITO and platinum are expensive materials that need to be replaced with cheaper alternatives in large scale production of low-cost DSCs. We fabricated a flexible and completely carbon-based CE for DSCs based on electropolymerized ...

A composite film of nickel sulfide/platinum/titanium foil (NiS/Pt/Ti) with low cost and high electrocatalytic activity was synthesized by the use of an in situ electropolymerization route and proposed as a counter electrode (CE) catalyst for flexible dye-sensitized solar cells (FDSSCs). The FDSSC with the NiS/Pt/Ti CE exhibited a comparable power conversion efficiency of 7.20% to the FDSSC with...

Transition metal oxides (TMO) and their carbon composites have become a glittering upcoming material science candidate. Their interesting properties, such as meticulous morphology, plentiful availability, flexible surface chemistry along with outstanding mechanical, thermal, optical properties make them ideal for efficient photocatalytic dye degradation. An extensive range of TMO, are reviewed ...

We report a new photoanode for flexible dye sensitized solar cells based on a judicious combination of SnO(2) nanoparticles and ZnO nanotetrapods and the development of an effective low temperature fabrication technique of "acetic acid gelation-mechanical press-ammonia activation". A 4.91% efficiency has been achieved on an ITO-coated polyethylenenaphthalate (ITO/PEN) substrate under 1 sun equi...
