Chalcogenide Perovskites and Perovskite-Based Chalcohalide as Photoabsorbers: A Study of Their Properties, and Potential Photovoltaic Applications

Abstract

In 2015, a class of unconventional semiconductors, Chalcogenide perovskites, remained projected as possible solar cell materials. The MAPbI3 hybrid lead iodide perovskite has been considered the best so far, and due to its toxicity, the search for potential alternatives was important. As a result, chalcogenide perovskites and perovskite-based chalcohalide have recently been considered options and potential thin-film light absorbers for photovoltaic applications. For the synthesis of novel hybrid perovskites, dimensionality tailoring and compositional substitution methods have been used widely. The study focuses on the optoelectronic properties of chalcogenide perovskites and perovskite-based chalcohalide as possibilities for future photovoltaic applications.

Understanding the growth mechanism of BaZrS3 chalcogenide perovskite thin films from sulfurized oxide precursors

“…From the materials research perspective, new solutions based on abundant and non-toxic resources need to be developed for sustainable future deployment of solar energy on a large scale. With this in mind, chalcogenide perovskites are recently explored as a new wide-bandgap alternative for thin film photovoltaic (PV) absorbers [1][2][3]. They mostly contain Earth-abundant and non-toxic elements and they exhibit extraordinary chemical and thermal stability [4].…”

High‐Temperature Equilibrium of 3D and 2D Chalcogenide Perovskites

“…Chalcogenide perovskites (CPVK) have recently been proposed as possible nontoxic alternatives to lead-based perovskites for photovoltaic applications thanks to their promising optoelectronic characteristics, including a bandgap that is suited for tandem solar cell applications. [1][2][3][4] Chalcogenide perovskites follow the formula ABX 3 with A, B, and X representing an alkaline earth cation (2þ), a transition metal cation (4þ), and a chalcogenide anion (2-), respectively. [5][6][7] The most studied compound in this family is BaZrS 3 , but other compositions have been reported.…”

Controlled Growth Cu2S Nanoarrays with High-Performance Photothermal Properties

“…Among them, chalcogenides possessing unique optical and electronic properties have been emerging as prominent research areas in materials science, chemistry, and nanotechnology [ 2 , 3 ]. Specifically, typical chalcogenides such as MoS 2 , Cu 2 S, WS 2 , TaS 2 , MoSe 2 and WSe 2 have been demonstrated to be suitable candidates in electronics [ 4 ], sensors [ 5 ], energy storage and conversion [ 6 ], biomedicine [ 7 ], and solar cell applications [ 8 ].…”
