Special Issue Information

Dear Colleagues,  

Organic solar cells (OSCs) possess the advantages of flexibility, low cost, light weight, and versatility for large-scale fabrication. In recent years, thanks to the rapid development of non-fullerene acceptor materials, the performance of OSCs is booming, with power conversion efficiencies (PCEs) reaching as high as 16 ~ 17%. In addition to the active layer, which generates excitons and charges, the interfaces are also important, since they play important roles in charge separation and collection. The hole transport layer (HTL) and electron transport layer (ETL) can help in extracting one type of charge carrier and blocking the opposite and are essential for achieving a high efficiency. The materials used as HTLs include poly (3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) and metal oxides (e.g., MoO3, V2O5). The most widely used ETLs are metal oxides (e.g. ZnO, TiO2), low-work-function metals (e.g., Ca), fullerene derivatives, and conjugated polyelectrolytes. To achieve an ideal interfacial contact, reduce electrical loss, and further improve the efficiency of polymer solar cells in a wide range of electronic applications, it is necessary to find more suitable polymer materials.

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. Polymers 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 2700 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.

A new type of polymer matrix electrolyte based on modified polybutadiene (modified PB) was developed for dye-sensitized solar cells (DSSCs) to improve their stability. The modified PB was fabricated by cross-linking the reaction of polybutadiene with siloxane groups as a substitute sol-gel process. A DSSC device using the modified PB matrix electrolyte showed an open-circuit voltage of 0.64 V, a short-circuit current density of 15.00 mA/cm2, and a fill factor of 0.58 under photointensity of 100 mW/cm2 at AM 1.5, consequently leading to an overall solar energy conversion efficiency of 5.49%. The DSSC device using the modified PB matrix electrolyte improved the conductivity, and the charge transfer ability showed the outstanding stability of the device. Full article
