Dalian Institute of Chemical Technology has prepared high-efficiency large-area perovskite solar module cells

Recently, the team of researcher Liu Shengzhong and Ph.

The slit coating technology has become one of the deposition technologies with industrialization prospects in the field of perovskite solar cells due to the advantages of low cost, large production volume, and good continuity

The researchers used slit coating deposition technology, combined with high pressure nitrogen-extraction strategy, to effectively control the nucleation and grain growth of the perovskite film, and drive the formation of a stable mesophase, so that the deposition and preparation are uniform Dense perovskite film

The study shows that slit coating printing combined with high-pressure nitrogen extraction technology is a high-efficiency, wide-window, low-cost, and expandable area perovskite solar cell preparation technology, which is beneficial to promote the development of slit coating deposition technology.
