Special Issue Information

Dear Colleagues,

Energy efficiency in buildings has attracted a significant research interest recently, driven by the fact that about 40% of the total energy consumption worldwide is attributed to the building sector. In this context, the idea of a “zero energy building” has emerged that can be served through the dynamic control of thermal loads with the use of “smart” windows. These windows adapt to the prevailing weather conditions in real time, changing their appearance from transparent to opaque in a reversible manner. By appropriate control, they can achieve the rejection of excess solar radiation entering the buildings at noon and adequate insolation during the morning and afternoon hours. Electrochromics comprise the most mature technology of “smart” windows with a considerable potential for energy savings. Indeed, their incorporation in buildings could lead to a decrease of 30% of the total annual energy consumption, a significant step towards the goal for “zero energy buildings”. They have already found their way to the windows market, which constitutes a multibillion $ enterprise.

Apart from the typical electrochromics described above, novel electrochromic materials and technologies have appeared in recent years. These include nanostructured and composite electrochromic materials, the near infrared “plasmonic” electrochromics, and a multitude of electrochromic polymers with different colors or even with multicolor features. Furthermore, new multifunctional devices have emerged, such as the photoelectrochromic hybrids with integrated solar cells that drive the coloration of the smart window and simultaneously harness solar energy, or electrochromics with charge storage capabilities acting as batteries or supercapacitors. Such devices are being researched extensively at the moment and provided they overcome scalability and stability issues, some of them are going to be the “smart” window products of tomorrow.

This Special Issue aims to survey the recent progress in the area of electrochromic materials and their applications. The articles presented in this Special Issue will cover all the relevant topics, ranging from materials preparation and characterization, to device fabrication and testing. This Special Issue will offer a unique glimpse of what has been achieved and what is forthcoming in the field of electrochromics.

The following topics will be covered:

  • Synthesis and characterization of materials used in electrochromic applications:
    • Inorganic electrochromic compounds
    • Nanostructured or composite electrochromic materials
    • Electrochromic polymers
    • Ion storage layers
    • Electrolytes
  • Other chromogenic materials, such as:
    • Thermochromics
    • Gasochromics
  • Fabrication and testing of related devices, such as:
    • Battery type electrochromics
    • Redox type electrochromics
    • Near infrared electrochromics
    • Photoelectrochromics
    • Devices with charge storage capabilities
    • Electrochromic batteries.
  • Other relevant subjects, such as:
    • Theoretical investigations and simulations
    • Electronic controllers (hardware and software)
    • Assessment of performance in real operating conditions

It is my pleasure to invite you to submit review articles, original papers and communications for this Special Issue of "Advances in Electrochromic Materials and Related Devices".

Solar-driven electrochromic smart windows with energy-storage ability are promising for energy-saving buildings. In this work, a flexible photoelectrochromic device (PECD) was designed for this purpose. The PECD is composed of two flexible transparent conductive layers, a photocatalytic layer, an electrochromic material layer, and a transparent electrolyte layer. The photocatalytic layer is a dye-sensitized TiO2 thick film and the electrochromic layer is a WO3 thin film, which also possesses a supercapacitive property. Under illumination, dye-sensitized TiO2 thick film realizes photo-drive electrochromism that the WO3 changes from colorless to blue with large optical modulation. Meanwhile, the PECD has an electrochemical supercapacitance showing an energy storage property of 21 mF·cm−2 (114.9 F·g−1 vs the mass of WO3), stable mechanical performance and long cycle performance. The PECD can effectively adjust the transmittance of visible and near-infrared light without any external power supply, realizing zero energy consumption, and can convert solar energy into electrical energy for storage.
