Perovskite Cells: Hope for Future Energy-Shanghai Yangmi

With the increasing global energy demand and the improvement of environmental protection awareness, finding efficient, clean and renewable energy has become an urgent need in today's world. Perovskite cells, as an emerging solar cell in recent years, are gradually becoming the focus of scientific and industrial circles due to their excellent photoelectric conversion efficiency and low production costs.

Perovskite cells, as the name suggests, are solar cells that use perovskite material as a light-absorbing layer. Perovskite is not a mineral, but a crystal structure commonly referred to by the scientific community as titanium calcium oxide. This material was discovered in the Ural Mountains of Russia in 1839 and named after the late Russian mineralogist Lev Perovski. In recent years, with the deepening of research, scientists have discovered that applying perovskite materials to solar cells can significantly improve the efficiency of the battery.

The working principle of perovskite cells is mainly based on the photoelectric effect. Under light, the perovskite material absorbs photons, creating electron-hole pairs. These electrons and holes are then transported to the electron transport layer and hole transport layer of the battery respectively, eventually forming a current in the external circuit. The structure of a perovskite cell usually includes conductive glass, electron transport layer, perovskite light absorption layer, hole transport layer and metal electrode.

Perovskite cells have gradually become a reliable new energy source in people's minds due to their high photoelectric conversion efficiency and low production costs.

However, ultrasonic spraying technology plays a key role in the preparation of perovskite cells. As an emerging solar cell, perovskite cells have attracted much attention due to their high photoelectric conversion efficiency, low production costs, good stability and longevity. Ultrasonic spray technology is a method that can accurately control film deposition.

Through ultrasonic spraying, the perovskite solution can be atomized into tiny droplets and evenly coated on the substrate to form a high-quality perovskite film. This technology not only improves the uniformity and crystal quality of the film, but also effectively improves the photoelectric conversion efficiency of solar cells. Compared with the traditional spin coating method, ultrasonic spraying is more suitable for large-scale industrial production, laying a solid foundation for the commercial application of perovskite batteries.

Therefore, ultrasonic spraying technology has become an indispensable part of the perovskite battery preparation process and is of great significance in promoting the development of perovskite battery technology.

As a new type of solar cell, perovskite cells are gradually becoming the hope of future energy due to their advantages such as high efficiency, low cost and environmental protection. With the deepening of research and the continuous maturation of technology, it is believed that perovskite batteries will play an increasingly important role in the future energy field.
