Special Issue Information
Dear Colleagues,
The development of non-fullerene acceptors, such as ITIC and Y6, is playing a vital role in polymer solar cells (PSCs) and all small molecule organic solar cells (SM-OSC), with the engineering of innovative devices based on them pushing power conversion efficiency (PCE) up to 18% and 15%, respectively, offering great potential for commercialization. Despite the outstanding achievements in polymer donor and small molecule acceptor systems, however, batch-to-batch variations of polymer donors are still quite challenging, leading to reduced device performance reproducibility. Small-molecule donors have a well-defined chemical structure, easy purification, and high crystallinity, and therefore excellent batch-to-batch reproducibility. It is thus necessary to pay more attention to SM-OSCs, especially as, despite the efficiency of over 15% achieved for SM-OSCs, there seem to be too few works focused on their stability, including storage, thermal, and photo stability. In addition, compared to conventional device structures, inverted devices exhibit improved environmental stability. The migration of indium and tin ions into the active layer caused by PEDOT:PSS in conventional structures leads to electrode degradation but is eliminated for inverted devices due to its robust metal–oxide interfacial layers. However, there have only been few cases of SM-OSCs using an inverted structure achieving a better device performance.
In this Special Issue, all manuscripts related to research and application of organic polymer solar cell materials are welcome. The stability of all small molecule organic solar cells, including storage, thermal, and photo stability, and using inverted device structure fabricated SM-OSCs, are invited.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all 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. 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.
