Method for revealing the residual tensile stress inside perovskite films
Flexible perovskite solar cells have been favored in various application scenarios due to their high efficiency, lightweight, and flexibility. Their application range includes BIPV (Building Integrated Photovoltaics), public facilities, 3C electronic consumer products, and various lighting surfaces.
However, flexible perovskite solar cells face not only the same environmental negative factors as rigid perovskite solar cells but also the stress issues caused by being in a bent state during actual applications. Recently, our company collaborated with Xiamen University to propose for the first time an effective method to enhance the stability of flexible devices under bending by adjusting the residual stress of the perovskite film in the internationally renowned journal Journal of Energy Chemistry (Doi: 10.1016/j.jechem.2024.11.008).Adjusting the residual stress of the perovskite film.This work specifically utilized a new type of molecular additive jointly synthesized by our company and Xiamen University (Patent Publication No.: CN117979799A) to alleviate the residual tensile force within the perovskite film by compressing the perovskite lattice structure, thereby improving the stability of the film and enhancing the stability of the perovskite film in a bent state, making it suitable for various application scenarios.
Dazheng Micro-Nano, as a leading enterprise in the precision manufacturing of flexible perovskite film batteries in China, is not only committed to the customized development of production line manufacturing equipment and the manufacturing of flexible lightweight perovskite batteries but also pays more attention to improving the efficiency and aging mechanisms of perovskite batteries. Through new material development and device process optimization, we are solidly advancing the industrialization of flexible lightweight perovskites.
