Solar cells represent a promising innovation in energy storage, offering not only exceptional cleanliness and low cost but also a high degree of flexibility, rendering them widely applicable. In recent years, scientists have dedicated substantial efforts to enhancing the performance of solar cells, aiming to drive sustainable development and promote clean energy applications. One approach that has garnered significant attention is strain engineering, which involves the adjustment of material microstructure and organization through mechanical tensile or compressive strain, ultimately serving to enhance the mechanical properties and performance stability of materials. This paper aims to provide a comprehensive review of the latest advancements in the application of strain engineering in solar cells, focused on the current hot research area—perovskite solar cells. Specifically, it delves into the origins and characterization of strain in solar cells, the impact of strain on solar cell performance, and the methods for regulating stable strain. Furthermore, it outlines strategies for enhancing the power conversion efficiency (PCE) and stability of solar cells through strain engineering. Finally, the paper conducts an analysis of the challenges encountered in the development process and presents a forward-looking perspective on further enhancing the performance of solar cells through strain engineering.

The pervasive issue of metal corrosion in various industrial environments, especially in marine settings, incurs significant economic costs and hazardous failures. Traditional protection methods, although diverse, fall short in durability and environmental adaptability, necessitating advanced solutions, such as two-dimensional (2D) materials, including graphene, layered double hydroxides, boron nitride, MXenes, and MoS2. These materials offer exceptional barrier properties against corrosive agents due to their high surface area and minimal thickness, enhancing the lifespan and reliability of metal assets under harsh conditions. Innovations such as self-repairing coatings and advanced application techniques, such as automated spraying and rapid photocuring, further augment their effectiveness. In this Review, recent advancements in the development and application of 2D material-enhanced coatings are reviewed, underscoring their potential in revolutionizing marine corrosion protection through improved performance metrics and sustainability. The challenges and prospects of these novel materials are also discussed, highlighting the need for further research to overcome application hurdles and realize their full potential in industrial uses.
