Ultrasonic spraying of perovskite

Research progress on the preparation of perovskite solar cells by spraying technology -- New energy -- YMUS ultrasonic spraying

Ultrasonic spraying technology in the preparation of perovskite solar cells has gradually received attention and research. Compared with traditional spraying technology, ultrasonic spraying technology can achieve a more uniform and dense perovskite film coating, improving the performance of solar cells.

Research progress of ultrasonic spraying technology in the preparation of perovskite solar cells:

1) Liquid preparation and stability: Ultrasonic spraying technology requires the preparation of stable perovskite precursor liquid. Ultrasonic dispersion was used to improve the uniformity and dispersion of perovskite precursor liquid, and the stability of the liquid was improved by adjusting the proportion of solvent, additive and perovskite material.

2) Optimization of spraying parameters: Spraying parameters during ultrasonic spraying have an important impact on the morphology and properties of perovskite films. The uniform and dense perovskite film was obtained by adjusting the ultrasonic power, spray distance, spray speed and spray Angle.

3) Substrate adaptability: Ultrasonic spraying technology is suitable for many types of substrate materials, including glass, plastic and metal. By adjusting the energy of ultrasonic spraying and the wettability of substrate surface, the adhesion and optical transparency between perovskite film and substrate are improved.

4) Defect repair and annealing treatment: the perovskite film prepared by ultrasonic spraying may have defects and incomplete crystallization. By annealing treatment and subsequent heat treatment methods, defects are repaired and crystallization of perovskite films is improved, thereby improving battery performance.

YMUS ultrasonic spraying technology innovates the first ultra-high temperature pyrolysis spraying machine in China in the preparation of perovskite solar cells. The difficulty of process control, the improvement of preparation efficiency and stability, further research and exploration to realize the commercial application of ultrasonic spraying technology in the field of perovskite solar cells.
