Special Issue Information

Dear Colleagues,

As energy consumption and climate warming are progressively increasing, many energy conversion techniques (e.g., water electrolyzers, photo-electrolyzers, fuel cells, metal-air batteries, and CO2/N2 reduction) have been developed, which can mitigate the energy crisis and climate problems. Therefore, the development of new photo-electrocatalytic materials to solve these problems is urgently needed. Thanks to the efforts of countless researchers like you all over the world, new materials are changing with each passing day. New progress and information should be organized and shared promptly with the international community, which will effectively promote the rapid development of related research. Therefore, we are looking forward to receiving your latest unpublished original research results on the application of nanomaterials in energy conversion and environmental treatment. Your high-quality articles will be published in this Special Issue after rigorous peer review. I extend my warm invitation for research papers from a broad range of topics related to nanomaterials aiming at future energy resources, low-emission energy conversion, energy storage, energy efficiency, air emission control, air monitoring, air cleaning, and many other related applications. Our team will always work hard for the rapid and extensive dissemination of your valuable research results and recent developments in the field of energy and the environment.

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 2300 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.

Embedding nanoparticles (NPs) in the buffer layer of bulk heterojunction polymer solar cells (BHJ PSCs) excites the surface plasmonic polaritons and enhances the pathlength of the light in the solar cells. On the other hand, embedding NPs in the active layer significantly improves absorption and increases the production of electron-hole (e-h) pairs in BHJ PSCs. Increasing the volume ratio of NPs embedded in BHJ PSCs enables the direct interfacing of the NPs with the active layer, which then serves as a charge recombination center. Therefore, this study integrates the aforementioned phenomena by exploiting the effects of embedding plasmonic [email protected] NPs in the buffer and active layers of PSC and then determining the optimum volume ratio of [email protected] NPs. The results show the absorption is increased across the 350–750 nm wavelength region, and the PCE of the device with embedded [email protected] in two locations is enhanced from 2.50 to 4.24%, which implies a 69.6% improvement in the PCE in comparison to the reference cell. This improvement is contributed by the combined localized surface plasmon resonance (LSPR) effects of multi-positional [email protected] NPs, spiky durian-shaped morphology of [email protected] NPs, and optimized volume ratio of [email protected] NPs embedded in the PEDOT: PSS and PTB7:PC71BM layers.
