Over the past several decades, photovoltaic (PV) technologies have demonstrated continuous progress and cost reduction. Nevertheless, PV technologies currently only provide for approximately 1% of the global energy consumption, and considerable gains can be achieved when the solar panels become more efficient and much cheaper. Although highly efficient solar cells are currently available, high manufacturing cost prevents these solar energy devices from obtaining a larger share of the energy market. Therefore, producing highly efficient solar cells with low-cost materials and techniques is highly desirable. Novel methods should be able to increase the efficiency of solar cells made of conventional and new materials in a realistic manner. From the solar cell fabrication point of view, a simple, fast, low-temperature, and clean process is required for such novel methods. This makes bottom-up methods such as the use of nanoparticles realistic and important, and therefore the focus of this Special Issue is on “Nanoparticles for Photovoltaics”. Nanoparticles can be used as constituents (e.g., quantum dots), or for light management structures (e.g., plasmonic and Mie scatterers). Light management methods have been investigated with respect to conventional solar cell compositions. New materials such as the kesterites and perovskites are now awaiting such explorations. A recent addition to these novel concepts is the light budgeting method using up and down converter particles. Both physical (e.g., with gas aggregation nanoparticle sources) and chemical nanoparticle preparation will likely be used in solar cell device fabrication. With this Special Issue, we aim to cover all of these promising topics related to the use of nanoparticles to increase solar cell performance.

Title: Aqueous-Based Binary Sulfide Nanoparticle Inks for Cu2ZnSnS4 Thin Films Stabilized with Inorganic Metal Chalcogenide Complexes
Author: Han Wang, Amrita Yasin, Nathaniel J. Quitoriano, and George P. Demopoulos
Abstract: Cu2ZnSnS4 (CZTS) is a promising semiconductor material for photovoltaic applications, with excellent optical and electronic properties while boasting a nontoxic, inexpensive, and abundant elemental composition. Previous high-quality CZTS thin films often required either vacuum-based deposition processes or the use of organic ligands/solvents for ink formulation, which are associated with various issues regarding performance or economic feasibility. To address these issues, an alternative method for depositing CZTS thin films using an aqueous-based nanoparticle suspension is demonstrated in this work. Nanoparticles of constituent binary sulfides (Cu2S and ZnS) are stabilized in the ink using a tin-based, metal chalcogenide complex (Sn2S64-). This research paper provides a systematic study of nanoparticle synthesis and ink formulation via the enabling role of the tin chalcogenide complex, the deposition of high-quality CZTS thin films via spin coating and annealing under sulfur vapor atmosphere, their structural characterization in terms of nanocrystal phase, morphology, and densification, and their optoelectronic properties analyzed via absorbance and photoluminescence spectra.
