Chemistry Innovatives in Perovskite Based Materials

Dear Colleagues,

Metal halide perovskites have attracted widespread research and development interest as their broad applicability and promising potential in photovoltaics, light-emission diodes, radiation detectors, and transistors.

Significant progress has been made in developing perovskite materials for solar cells, where efficiencies have increased rapidly from less than 10% to over 25% in the last decade. This has been achieved through discovering innovative materials and optimizing device architectures, such as tandem and perovskite/silicon hybrid solar cells. Moreover, the unique molecular structure and properties of perovskite materials, such as high color purity and brightness, have enabled their use in developing highly efficient and cost-effective light-emitting diodes and photodetectors. Despite these advances, challenges remain in the development of perovskite materials for optoelectronic devices, and continued research is required to address these challenges and to open up new possibilities for light harvesting and energy consumption, especially interms of Stability, Toxicity, higher efficiency and better performance in optoelectronic devices, and Scalability.

The development of perovskite based materials depends on a multidisciplinary approach that involves contributions from various fields of chemistry, including chemistry, physical chemistry, inorganic and organic chemistry, and chemical engineering. The molecular structure of perovskites influences their properties, including their optoelectronic properties, stability, and toxicity. The chemistry of perovskite materials involves the design and synthesis of new molecules, including their crystal structure and composition, to optimize these properties. The use of innovative synthetic techniques and new molecular designs in organic and inorganic chemistry has enabled the development of perovskite materials with improved stability, better optoelectronic properties, and reduced toxicity. Physical chemistry has also played a crucial role in investigating the photophysical properties of perovskite materials, including their absorption, emission, and carrier dynamics. These properties have been optimized through the design of new materials and device architectures, leading to higher efficiency and better performance in optoelectronic devices. Moreover, Chemical engineering has played a significant role in the scalability of perovskite based materials. Researchers have developed innovative processing techniques for producing perovskite materials on a larger scale, which has enabled the commercialization of perovskite solar cells. Continued research in this area is necessary to further improve the scalability of perovskite based materials and make them a practical and cost-effective solution for renewable energy.

This Special Issue aims to act as a forum for the dissemination of the latest information on the new advanced synthetic techniques and new designs of Perovskite Based Materials. These make the new molecules structure with better stability, more environmentally friendly, and better optoelectronic properties. We encourage authors to submit manuscripts in the form of a research paper or review in all respects above.
