Special Issue Information

Dear Colleagues, 

It is well noted that renewable energy from sunlight is a sustainable energy source capable of meeting global demand and an effective way to deal with environmental problems. Among various semiconductors, low-dimensional nanomaterials are broadly researched for application in light energy harvesting and photovoltaic devices. The high specific surface area, tunable morphological shapes, improved light absorption, and large charge carrier lifetime are particularly important for enhancing light energy harvesting and utilization ability. The surface chemistry and surface modification of nanomaterials are also essential for the improvement of their optoelectronic properties. We are pleased to invite you to contribute to the latest scientific and technological advances in this emerging field.

This Special Issue aims to provide a comprehensive overview of the development of state-of-the-art nanomaterials for light energy harvesting and photovoltaic devices, the strategies employed for improving the performances of nanomaterials for energy conversion, and to stimulate new interest in this field. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) nanomaterials, light energy harvesting, photovoltaics, renewable energy, energy systems, and solar energy conversion.

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. Nanomaterials 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 2900 CHF (Swiss Francs).

The Cu2Ni0.05Zn0.95Sn(S,Se)4 (CNZTSSe) films were synthesized by sol-gel combined with selenidation treatment. To further enhance the crystal quality of the film, the selenidation conditions were optimized, and the effects of selenidation time on the properties of the CNZTSSe films and devices were systematically studied. The results show that the crystallinity of the films increased remarkably with the increase of selenidation time. Under the optimum selenidation time of 15 min, smooth and dense films were obtained. Through the analysis of EDS results, it is found that Se occupies more S positions with the increase of selenidation time, which decreases the band gap of the film from 1.14 eV to 1.0 eV. In addition, the formation of Zn-related defects is effectively suppressed by Ni doping to enhance the open circuit voltage (Voc) of the CNZTSSe solar cells. When the selenidation time is 15 min, the CNZTSSe film has the highest carrier concentration of 1.68 × 1016 cm−3, and the best efficiency of the device prepared based on the film as the absorption layer is 5.0%, and the Voc is 337 mV.
