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.
Highlights
On earth, semiconducting materials are inexpensive and plentiful
Chalcogenide perovskite is a suitable photoabsorber with an ideal bandgap that would be beneficial for photovoltaic technologies
Wei X et al has described the development of BaZrS3 thin films to estimate its carrier densities, mobility, and absorption coefficient measurements, thereby these findings could theoretically release the group of perovskite chalcogenides for optoelectronics, for instance, photovoltaics, photodetectors, and light-emitting diodes, ensuring that BaZrS3 is a promising candidate [42]
Summary
On earth, semiconducting materials are inexpensive and plentiful. The application of these substances in solar cells for this purpose remains expedient and cheaper than photovoltaic technology based on silicon [1]. The Ruddlesden−Popper form perovskite chalcogenide, recently demonstrated, is the ideal bandgap for a solar cell with a single-junction in a solid crystalline Ba3 Zr2 S7 [27] Another area of interest where the perovskite family has provided rich chemical and structural possibilities is the reporting of chalcohalide perovskite that was original without lead integrated chalcogen and halogen negatively charged ions having a general formula of “A.B. Perovskites are well developed to create prospects for a wide variety of photonic, optoelectronic, and energy technologies, together with that of solar cells, photoelectrochemical systems, photodetectors, and based on the combination of ultra-high absorption coefficient and projected high mobility of the carrier along with tunable bandgap, solid thermal and aqueous stability, benign and earth-abundant materials. The study focuses on the optoelectronic properties of chalcogenide perovskites and perovskite-based chalcohalide, taking into account the limitations of chalcogenide perovskite and presenting solutions for them to become potential perovskites for future photovoltaic development and to estimate the photovoltaic performance of perovskite-based chalcohalide in an attempt to establish possibilities for synthesis recommendations with their perovskite-based low dimensionality of potential 3D perovskite-based chalcohalide equivalents of both MASbSI2 and MABiSI2
