Dye-sensitized solar cells (DSSCs) provide a technique and economic alternative concept to present p–n junction photovoltaic devices. For a DSSC, light is absorbed by a sensitizer, which is anchored to the surface of a wide-band semiconductor. Charge separation takes place at the interface via photo-induced electron injection from the dye into the conduction band of the semiconductor. Although many types of fabrication techniques for multiscale structure materials have been developed, there is still a wide space for more simple strategies with the development of nanotechnology. Not only for homogeneous new materials, multiscale structure functional materials have a variety of applications, which can be used as water collecting materials, structure control color materials, energy conversion materials, responsive structure materials, photovoltaic devices materials, and so on.

We invite investigators to contribute original research articles as well as review articles that will stimulate the continuing efforts to understand the theory of photoelectric conversion and new materials and device fabrication methods. We are particularly interested in articles introducing new materials or new fabrication methods for DSSC. These may inspire both theoretical interests and industrialization potentials. Potential topics include, but are not limited to:

• Recent developments in dyes
• Advances in working electrodes
• Latest technologies for device fabrications
• Recent advances in new electrolytes
