Dear Colleagues,

Next-generation solar cells such as dye-sensitized solar cells, quantum-dot-sensitized solar cells, perovskite solar cells, etc. have become the most promising photovoltaic technologies to supply renewable green energy. Counter electrodes for next-generation solar cells have an important role in improving the energy-conversion efficiency of photovoltaic devices. There are various types of counter electrode catalysts for next-generation solar cells, including metal, metal compounds, carbon materials, nanohybrid materials, polymers, composites, etc. This Special Issue aims to provide a discussion of the design and synthesis of the catalysts, the characterization and stability of the devices, as well as calculations of catalytic activity, electrical conductivity of counter electrodes. We welcome submissions in the form of full papers, communications, and reviews. Potential topics include, but are not limited to:

• Design, preparation, theoretical calculation, and stability evaluation of counter-electrode catalysts.
• Low-cost counter-electrode catalysts of next-generation solar cells.
• Commercial applications of next-generation solar cells.
• Green technologies in next-generation solar cells.
• Other applications of electrode catalysts in energy storage, sustainability, fuel cells, hydrogen production, solar-driven steam generation and photocatalysis.

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. Nanomaterials 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 2900 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.
