Special Issue Information

Dear Colleagues,

The Guest Editor is inviting submissions for a Special Issue of Energies on “Solution-Processed Organic Photovoltaic Devices”. Solution-processed organic solar cells are in their third decade of research and development. Well-performing photovoltaic devices were fabricated using a variety of organic compounds, many of which were synthesized specifically for this application, both polymer and small molecular compounds. A number of device architectures were invented, in many cases using inorganic layers as critical components for the interface and electrode formation. In parallel, methods for large area and high throughput fabrication were explored, bringing new challenges for materials, fabrication methods, and device architectures. This tremendous development in organic photovoltaics resulted in frequent reports of efficiencies above 10% for laboratory prototypes, and the advancement continues.  

This Special Issue focuses on strategies enabling the large-scale fabrication of organic solar cells with performance and functionality relevant for large-scale applications. Topics of interest include but are not limited to:

  • Materials and methods for deposition of bulk-heterojunction, interfacial, and electrode layers suitable for large area, and large throughput fabrication of organic solar cells;
  • Device architectures enabling large area fabrication;
  • Sustainable alternatives for the glass/ITO substrate and for thermal evaporation of metal electrodes;
  • Non-chlorinated solvent systems;
  • Non-fullerene electron acceptor materials;
  • Interactions between the individual components within the bulk-heterojunction;
  • Formation of the interfaces to the bulk-heterojunction, and new insights into the physicochemical processes leading to formation of efficient interfaces;
  • Studies of the interface between organic and inorganic compounds;
  • Charge carrier recombination and strategies to lower its effect on device performance;
  • Materials and material systems for optimal utilization of the solar spectrum;
  • Exploration of the limits for purification of the materials and their relevance for the device performance and stability;
  • Lifetime studies and degradation mechanisms;
  • Lamination of device structures;
  • Effective structuring and encapsulation of devices;
  • Integration of organic photovoltaics in architectural elements;
  • Organic photovoltaics for specific applications, not necessarily with top efficiency.

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 papers will be 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. Energies 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 2000 CHF (Swiss Francs).
