Special Issue Information
Dear Colleagues,
The use of renewable energy is fundamental within the 2030 Agenda for Sustainable Development, adopted by the United Nations Member States in 2015. Sustainable development goal (SDG) 7 focuses on "ensuring access to affordable, reliable, sustainable and modern energy for all" by 2030. This is only seven years away, and the urgency of our efforts towards this goal is obvious. Among the sustainable resources on Earth, solar energy provides an unlimited source of free energy which has the potential to meet global energy demands. Photoconversion using Grätzel-type dye-sensitized solar cells (DSCs) is well established as a technology, and state-of-the art DSCs use metal-free (organic) compounds or metal coordination compounds as dyes. The greatest emphasis has been on the development of n-type DSCs, and those sensitized with octahedral ruthenium(II) complexes or porphyrin- or phthalocyanine-based dyes containing zinc(II) achieve some of the highest photoconversion efficiencies. However, the development of dyes based on other metal coordination compounds is also an active area of interest, and the most notable are N-heterocyclic iron(II) and bis(diimine)copper(I) dyes, which have shown progress in the applications of dyes containing Earth-abundant metals. The role of metal coordination compounds in DSCs is not restricted to sensitizers. Although one of the most conventional redox shuttles is I3–/I–, coordination complexes containing redox-active metal centres have significant potential; Cu2+/Cu+ redox shuttles have drawn considerable attention because, when combined with appropriate dyes, they can lead to DSCs exhibiting open-circuit voltages (VOC) values greater than 1000 mV. Papers and reviews in all areas of the use of metal coordination compounds in DSCs, including p-type and tandem DSCs, are welcomed for this themed issue of Molecules.

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. Molecules 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 2700 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.
