Abstract
Perovskite films with excellent photoelectric properties play a significant role in fabricating high-performance solar cells. Magnetron sputtering is a commercially available and highly reliable technique that is highly attractive for applications in the production of perovskite films. Here, the ion deposition of the step-by-step sputtering process and the continuous sputtering process was systematically explored to realize the controlled ion deposition and crystallization of sputtered perovskite films. We found that the deposition rate of organic components in the initial sputtering stage is greater than that of inorganic components, leading to the ion ratio of perovskite thin films being accurately regulated by adjusting the sputtering time. Furthermore, the injected content of methylammonium bromide will significantly affect the ion ratios and crystal structures of the sputtered perovskite films. The efficiency and stability of sputtered perovskite solar cells can be enhanced significantly by optimizing the sputtered processes and improving the crystallization, which lay a solid foundation for further study of the preparation of perovskite solar cells by magnetron sputtering.
期刊介绍：
ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times.
