Special Issue Information
Dear Colleagues,
In the past few years, the development of non-fullerene acceptors represented by Y6 has greatly improved the power conversion efficiency of organic solar cells. At present, the power conversion efficiency of organic solar cells exceeds 19%, showing their broad commercial prospect. On the one hand, the improvement in the photoelectric conversion efficiency of non-fullerene solar cells benefits from the good photon absorption characteristics of non-fullerene materials in the near-infrared region; on the other hand, this is attributed to their unique photophysical properties, which differ from those of fullerene solar cells. For example, the exciton diffusion length of the newly emerging Y acceptors can exceed 50 nm, which is much longer than that of traditional acceptors and conducive to exciton dissociation in non-fullerene solar cells. In addition, the low driving force and better device stability in non-fullerene organic solar cells enables non-fullerene solar cells to be exploited for their advantages in practical applications. However, the physical processes underlying these issues need to be further clarified. In this Special Issue, we aim to discuss various topics related to the photophysical mechanism in non-fullerene solar cells, including advances in device physics and photoelectric conversion dynamics.
Both original research articles and reviews are welcome for this Special Issue. We look forward to receiving your contributions.

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.
