Spraying Perovskite Material

Spraying perovskite materials to prepare perovskite-type solar cells

At present, solar cells with a perovskite structure have high application prospects. The light-absorbing material in the cell structure, perovskite, has a high extinction coefficient, and solar energy below 800nm ​​can be fully absorbed by a few hundred nanometers thick film. Compared with silicon batteries, perovskite absorbs green and blue light significantly stronger. Moreover, the crystallinity of the perovskite crystal is almost perfect, and the carrier recombination is greatly reduced, and the carrier diffusion length increases accordingly. The perovskite solar cell can exhibit excellent performance and these characteristics are closely related. However, perovskite-type solar cells still have many problems to be solved urgently, such as battery stability, battery life, how to prepare large areas and so on.

Spraying Perovskite Material

Our company provides an ultrasonic spraying machine for a university to spray perovskite materials on copper foil substrates. The spraying area of ​​our company’s ultrasonic spraying machine is 600*600mm, and the spraying thickness is in the range of 2-15um. The film prepared by spraying The uniformity is high, and the uniformity measured through experiments is also high, which is of great significance to the development of a continuous and stable spraying process for preparing perovskite-type solar cells.
