Special Issue Information
Dear Colleagues,
Since the early 1990s, the field of organic photovoltaic materials and devices has undergone rapid and impressive developments in both materials synthesis, device processing and characterization. Following initial studies on photovoltaic energy conversion organic single and bilayer heterojunctions, the discovery of efficient exciton dissociation at bulk heterojunctions comprising inter-penetrating donor-acceptor networks has enabled the power conversion efficiency of present devices to exceed 10%. This, together with the solution processing and print patterning of organic semiconductor materials, will enable organic photovoltaics to become a viable technology in coming years. Building integrated organic photovoltaics is an application that has been demonstrated.
For any photovoltaic technology, the key requirements for long-term viability are the device cost, photovoltaic power conversion efficiency and the device lifetime. This Special Issue is focused on these three aspects of organic photovoltaics. Research and review articles addressing new p-type and n-type organic semiconductor for photovoltaics, fundamental aspects of exciton formation and dissociation, carrier transport, bulk heterojunction interface structure and effect of defects on device performance are topics within the scope of this Special Issue. Manuscripts dealing with novel device processing techniques and efficiency enhancement, such as plasmonic nanoparticles for light trapping are welcome. Research on degradation mechanisms and device passivation techniques, radical new concepts of energy conversion in organic photovoltaics and novel organic-inorganic hybrid device structures are especially of interest to this Special Issue.

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.
