AI Technical Summary

Technical Problem

In existing technologies, the fabrication methods of tandem perovskite solar cells are complex and difficult to adapt to industrial production. Furthermore, the preparation of the intermediate layer often employs non-volatile solvents and blade coating methods, which affect cell efficiency and cost.

Method used

A tandem perovskite solar cell was prepared using a full solution method and an atomic layer deposition method. The perovskite intermediate was dissolved by a volatile solvent to form a bottom and a top perovskite layer. An 18 nm to 22 nm thick SnO2 intermediate layer was deposited between the two layers to block water and oxygen and protect the perovskite layer structure.

Benefits of technology

This method enables the fabrication of tandem perovskite solar cells that is simple to operate, economical, and environmentally friendly. It improves cell efficiency, reduces costs, and ensures that the crystal structure of the perovskite layer remains unaffected, making it suitable for industrial production.
