Studies to improve the efficiency of dye-sensitized solar cells (DSSCs) include, but are not limited to, finding alternatives such as 2D layered materials as replacement counter electrodes (CEs) to the commonly used Pt. Herein, we report for the firs

Noble transition metal chalcogenide gold selenide is a relatively unexplored layered material. Herein, we report on the synthesis and characterization of polymorphic mixed-valence AuSe (Au1+Au3+Se2) by varying the sequence of the addition of the prec

We report on the synthesis of the less explored AuSe and investigate the influence capping agents; oleylamine (OLA), 1-dodecanethiol (IDDT), and oleic acid (OA) have on its structure and surface. TEM showed long belt-like structures for both OLA and

Uncapped nanocrystalline cuprous nitride (Cu3N) decomposes spontaneously to CuO at room temperature due to the presence of water and oxygen in the atmosphere. Long-chain capping molecules have been successfully used to cap and protect the core nanocr

Herein we report on a novel one-step synthesis of copper-rich Cu3N, Cu2S and Cu9S5 nanoparticles by using the surfactant dodecanethiol as a sulfur source to substitute the nitrogen in Cu3N using the Pearson acid-base concept. The Cu3N nanoparticles a

Indium sulfide is an emerging material for solar cell application and for this reason it has attracted much attention. Herein we report on the growth development of β-indium sulfide nanoparticles with reaction time. The nanostructures were synthesiz
