Advances in Organic and Perovskite Solar Cells

Dear Colleagues,

Organic Solar Cells (OSCs) represent an outstanding class of photovoltaic technology, which has the potential to provide good Power Conversion Efficiencies (PCE), employing cheap, easily tunable polymeric or small molecule organic materials. In addition, these materials are compatible with industrial processes, thus, indicating potential low-cost upscaling. During the last few decades, a great deal of research has shed light on the operation principles of OSCs and has allowed the optimization of materials and devices. Thus, ten years ago, highly-efficient devices were obtained by employing blends of low-bandgap polymers and PCBM.  Nowadays, the employment of non-fullerene acceptors in blends with donor polymers has allowed the obtention of a PCE over 13% (J. Am. Chem. Soc., 2017, 139 , 7148–7151). Perovskite-based solar cells, have revolutionized the photovoltaic field in the last ten years. An impressive leap in PCE from 3% in 2009 to 23% in 2018 has attracted the attention of many researchers and industries, which are now fully devoted to the optimization of the stability of these interesting devices.

In this Special Issue, we would like to cover all important aspects concerning OSCs or PSCs, including novel materials, photopysical investigations, stability measurements, or innovations in device architectures.

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 250 words) can be sent to the Editorial Office for assessment.

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.
