Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit articles that focus on the use of oxide nanomaterials in solar cell applications.

Oxide nanomaterials are known for their numerous and diverse applications, which range from common products such as sunscreens to advanced devices such as photovoltaic cells and include, among others, a series of environmental and biomedical applications, such as the photocatalytic degradation of pollutants, water purification, biosensing, and drug delivery. 

This Special Issue aims to present a comprehensive and up-to-date overview of oxide nanomaterials for solar cell applications, which can act as both an introduction for newcomers to this field and as a valuable resource for experienced researchers at the forefront of the field.

This Special Issue will especially focus on the synthesis and analysis of 0D- (cluster, single atom, etc.), 1D- (nanowire, nanorod, nanotube etc.), 2D- (nanoplate etc.), and 3D (nanoparticle, nanoflower, etc.)-structured nanomaterials for electrochemical energy conversion systems such as solar cells, including the development of computational material design and identifying reaction mechanisms. Other topics not on the list of specified topics are also welcomed if they are related to the theme of the Special Issue.

We look forward to receiving your contributions.

Dr. Jing Zhang

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 poor film stability of Sn-Pb mixed perovskite film and the mismatched interface energy levels pose significant challenges in enhancing the efficiency of tin–lead (Sn-Pb) mixed perovskite solar cells. In this study, polyvinylpyrrolidone (PVP) is introduced into the PVK perovskite precursor solution, effectively enhancing the overall stability of the film. This improvement is achieved through the formation of robust coordination bonds between the carbonyl (C=O) in the pyrrole ring and the undercoordinated SnII and PbII, thereby facilitating the passivation of defects. Furthermore, the introduction of PVP inhibits the oxidation of tin (Sn), thereby enhancing the n-type characteristics of the perovskite film. This adjustment in the energy level of the PVK perovskite film proves instrumental in reducing interface energy loss, subsequently improving interface charge transfer and mitigating device recombination. Consequently, perovskite solar cells incorporating PVP achieve an outstanding champion power conversion efficiency (PCE) of 21.31%. Full article

In the quest for efficient and cost-effective photovoltaic absorber materials beyond silicon, considerable attention has been directed toward exploring alternatives. One such material, zincblende-derived Cu2ZnSnS4 (CZTS), has shown promise due to its ideal band gap size and high absorption coefficient. However, challenges such as structural defects and secondary phase formation have hindered its development. In this study, we examine the potential of another compound, Cu2ZnSnO4 (CZTO), with a similar composition to CZTS as a promising alternative. Employing ab initio density function theory (DFT) calculations in combination with an evolutionary structure prediction algorithm, we identify that the crystalline phase of delafossite structure is the most stable among the 900 (meta)stable CZTO. Its thermodynamic stability at room temperature is also confirmed by the molecular dynamics study. Excitingly, this new phase of CZTO displays a direct band gap where the dipole-allowed transition occurs, making it a strong candidate for efficient light absorptions. Furthermore, the estimation of spectroscopic limited maximum efficiency (SLME) directly demonstrates the high potential of delafossite-CZTO as a photovoltaic absorber. Our numerical results suggest that delafossite-CZTO holds promise for future photovoltaic applications. Full article
