Special Issue Information

Dear Colleagues,

“Affordable and clean energy” has been set up as one of the 17 Sustainable Development Goals in the Envision 2030 agenda by the United Nations, urgently calling for efficient utilisation of energy in different forms. Articial photonic structures, including plasmonic structures, photonic crystals and metamaterials, offer an unparalleled platform for both energy harvesting and management. By virtue of the recent advancement in physics and nanotechnology, photonic structures with feature sizes comparable to or small than wavelengths have been achieved, endowing systems with unprecedented optical properties for a repertoire of energy-related applications, ranging from photovoltaics, thermophotovoltaics, photocatalysis, solar steam generation to light extraction from LEDs, radiative cooling, wireless powering and beyond.

This Special Issue aims to provide an interdisciplinary platform for researchers from both Photonics and Energy Harvesting and Management, offering a platform to showcase your works, providing an overview of the recent developments and strategies covering topics including (but not limited to) those stated above. Both original research articles and reviews are welcome.

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. Photonics is an international peer-reviewed open access monthly 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.

We propose a multi-materials solar absorber consisting of regularly arranged cross resonators made of Ni, and nanocylinders made of Ti on their four corners. The finite difference time domain (FDTD) method is used to study the absorption performance of solar energy, the inherent absorption mechanisms and influencing factors of the absorber submerged in water. The proposed absorber achieves a nearly perfect absorption in the wavelength range of 300–2400 nm with an average absorptance higher than 98%, indicating that most of solar energy will be harvested. In addition, the high absorptance in the solar spectrum originates from the plasmon resonances of cross resonators and the magnetic polariton from the interaction between cross nanostructures and multi-material nanocylinders. Moreover, our absorbers are insensitive to the polarization of light due to the symmetry of the structures, but sensitive to the incident angle of the light. Most significantly, our absorbers can effectively prevent heat loss via radiation heat transfer by lowering their emissivity in the infrared region. The present study demonstrates a new design strategy for perfect solar absorbers consist of simple nanostructures made from multi-materials, which promise potential applications of solar energy harvesting and solar steam generation for desalination and wastewater treatment.
