Special Issue Information

Dear Colleagues,

Photovoltaics are generally regarded as one of the most promising and environmentally friendly energy sources. Nanostructured photovoltaics have shown great potential as the future renewable energy source, with high efficiency and low-cost features.

This present Special Issue aims to highlight recent comprehensive research advances in nanostructured photovoltaics. This includes the development of novel nanostructured solar cells, newly developed nano-photovoltaic absorbers, advanced strategies to enhance light harvesting, advanced modeling analysis for nanostructured photovoltaics, and advanced system applications of photovoltaics.

We invite researchers to contribute original research or review articles related to recent advances in nanostructured photovoltaics. Potential topics include but are not limited to:

  1. Advances in silicon solar cells, e.g., PERC/PERT, TOPCON, HIT;
  2. Advances in single junction thin-film solar cells, e.g., perovskite, OPV, DSSC, CIGS/CZTS, CdTe, QDs;
  3. Advances in multi-junction tandem solar cells, e.g., perovskite–Si, perovskite–perovskite, perovskite–CIGS, III-V-Si, QDs-Si, OPV-Si;
  4. Advances in efficient light harvesting, e.g., up-conversion, down-conversion, plasmonics;
  5. Advances in photovoltaic applications, e.g., PV systems, building-integrated photovoltaics;
  6. Advances in photovoltaic modeling, e.g., device optical modeling, device electrical modeling, PV system modeling;
  7. Advances in photovoltaic cost analysis, e.g., device cost analysis, PV systems cost analysis.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Enhanced Photocatalytic Activity of Anatase/Rutile Heterojunctions by Lanthanum and Tin Co-Doping
by Xiaodong Zhu, Fengqiu Qin, Lili He, Yu Jiao and Wei Feng

Abstract
Anatase/rutile heterojunctions were prepared using the sol–gel method and modified by La/Sn single doping and co-doping. Sn doping promoted the transformation from anatase to rutile, while La doping inhibited the phase transformation. La and Sn co-doping showed an inhibitory effect. The co-doping of [...] Read more.
Anatase/rutile heterojunctions were prepared using the sol–gel method and modified by La/Sn single doping and co-doping. Sn doping promoted the transformation from anatase to rutile, while La doping inhibited the phase transformation. La and Sn co-doping showed an inhibitory effect. The co-doping of La and Sn did not increase visible-light absorption, but exhibited a synergistic effect on inhibiting the recombination of photogenerated electrons and holes, which improved the photocatalytic activity on the basis of single-element modification. The first-order reaction rate constant of La/Sn co-doped sample was 0.027 min−1, which is 1.8 times higher than that of pure TiO2 (0.015 min−1). Meanwhile, the mechanism of photodegradation of methylene blue (MB) by La/Sn co-doped anatase/rutile heterojunctions was discussed through electrochemical measurements and free-radical trapping experiments.

Organic photovoltaics (OPVs) differ from their inorganic counterparts because of inevitable electronic disorders and structural heterogeneity. Charge carrier traps are inevitable in organic semiconductors. A common failure mechanism of OPVs is the development of an S-shaped current density–voltage characteristic (J-V curve). Herein, we focus on investigating the underlying physical mechanism of S-shaped deformation of J-V curve of the inverted organic photovoltaic devices with bulk-heterojunction, proven by experiments with the n-doped electron extraction layer and numerical simulations assuming electron traps (0.1 eV deeper) in the electron extraction layer. The numerical simulations are quite consistent with the experimental results. In addition, the open circuit voltage induced by S-kink is exemplified to be enhanced after removing the electron traps in the interlayer by introducing a dopant of cesium carbonate. Full article
