Structure-Property Relationships in Organic Semiconductors

Dear Colleagues,

This special issue is motivated by the increasing research interest in synthesis, fabrication and characterization of organic semiconductors (OSCs) for several novel applications. The properties of OSCs– including relatively easy and inexpensive fabrication, light weight, mechanical flexibility and compatibility with stretchability, and non-toxic processing methods – open broad prospects for their applications in variety of industrial and technological areas including solar cells, light emitting diodes, and thin film transistors.

Polymer solar cells (PSCs) based on organic semiconductors can be fabricated in nontoxic form and can be a part of sustainable economy as they can overcome the concerns on environmental impact and toxicity.  Moreover, due to the wavelength tunability of donor and acceptor materials used in PSCs, semi-transparent devices can be fabricated. Such devices are useful for light harvesting applications in small buildings. As sunlight has 50% of its radiation in near infrared (NIR) region, exploring the organic semiconductors that can also absorb the NIR sunlight can provide a new avenue to produce inexpensive flexible solar cell. Therefore, it is a critical need to understand the opto-electronic processes in these materials in relation to the chemical structure of donor and acceptor molecules and morphological details of the donor-acceptor blend that underlie high-efficiency.

This special issue highlights the recent progress in the field of PSCs. Considering your significant contribution in this field, I hence cordially invite you to submit your research work in this special issue entitled “Structure-property Relationships in Organic Semiconductors”.

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. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.
