Dear Colleagues,

For a long time, the energy issue has been a core problem that must be faced by humankind for sustainable survival and development. To a certain extent, it is related to national economies, people’s livelihood, and national security.

Compared to other renewable energy sources, solar energy has an irreplaceable position in the development of new energy thanks to its environmentally friendly and inexhaustible nature. In the third generation of solar cells, polymer solar cells (PSCs) have attracted much attention from scientists due to their wide range of material sources, low cost, flexibility, translucency, and large-area manufacturing.

So far, with the continuous efforts of scientists in this field, the power conversion efficiencies (PCEs) of PSCs have reached 16%–18%, and their efficiencies are eventually expected to exceed 20%. It seems clear that research on PSCs has advanced to the level of commercial application. However, whether the problems of its efficiency, cost, and stability can be solved well is a decisive factor for the industrialization and practical application of PSCs. It is of great practical significance and research value to develop new types of donor and acceptor materials for high-efficiency, low-cost, and high-performance organic photovoltaic devices.

This Special Issue aims to provide a premier international platform for professions to discuss and present their most recent research in the design, synthesis, and performance improvements of solar cells. Submissions on other topics are also welcomed.

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. Materials 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 2600 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.
