Special Issue Information

Dear Colleagues,

Current trends in energy supply and use are patently unsustainable—economically, environmentally, and socially. We can—and must—change our current path and increase our use of sunlight as an energy resource, which is continually replenished, environmentally friendly, and easily usable by means of different solar technologies. There is a need to provide a solid analytical footing that enables the international community to move forward on a well-defined growth path from today to 2050, one that identifies solar coating materials, cross applications, and characterization milestones needed to realize the full potential of different solar technologies. Very often in the scientific community, there is an excessive sectorialization that, in my opinion, is detrimental to the success of the tremendously important goal of capitalizing solar energy.

As the Guest Editor of this Special Issue, I am writing to inquire as to whether you would consider contributing a communication, original research article or review paper on new solar materials treating the following topics:

  • Solar coatings for thermal plants working at different temperatures based on metamaterials and metasurfaces with spectrally selective behavior; new intrinsically absorbing materials; semiconductors with tailorable bandgap; textured transition metal surfaces; metal–dielectric interferential filters; cermet-based multilayers with sharp cut-off of optical reflectance between absorptive and emissive behavior.
  • Emerging photovoltaic solar materials including, but not limited to, utilization in devices such as organic photovoltaics (OPVs), dye-sensitized (DSSCs) and perovskite solar cells (PSCs) made from polymers, molecules, or (colloidal) precursors, among many other material classes such as oxides, chalcogenides, or silicides.
  • Aging of solar materials: modeling, simulation, and experimental tests at the nanoscale.
  • Advanced materials for thermal storage systems: phase change materials (PCM), pure salts, salt eutectics, metals and metal eutectics, nano-enhanced PCM, nanofluids.
  • Antisoiling coatings for solar applications.
  • Self-cleaning solar materials.
  • Catalytic solar coatings employed as alternative electrodes to platinum in the water-splitting process (e.g., transition metal nitrides in HER or OER reactions).

The Special Issue will promote a largely multidisciplinary approach. We are extending our invitation to contribute not only to experts in the field but also to other researchers with innovative proposals.

Thank you for your attention.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this study, a low-cost, scalable and robust process is proposed as an innovative method for coating solar mirrors with a self-cleaning, transparent in the full solar range and versatile material based on auxetic aluminum nitrides, previously obtained at the laboratory scale. This work presents the scaling-up of the fabrication process from the laboratory to prototypal scale and the preliminary results of outdoor self-cleaning solar mirror field tests in the demonstrative concentrating solar power (CSP) plant ENEASHIP located in Casaccia (Rome) ENEA Research Center. Prototypes with a size of 50 × 40 cm have shown stability in external conditions: no coating degradation occurred during the test campaign. Their washing restores the initial reflectance affected by soiling and the self-cleaning performance allows for the utilization of a reduced quantity of water for cleaning operations with respect to the uncoated glass of back surface mirrors. A similar self-cleaning AlN coating could be utilized on other solar components affected by soiling, such as the glass envelopes in heat-collecting elements, PV panels and other parts where a self-cleaning performance combined with an optical one is required.
