In the production process of perovskite solar cells, slit coating is one of the key processes; however, edge effects seriously affect coating uniformity, thereby impacting cell performance and efficiency.

As an emerging photovoltaic technology, perovskite solar cells are rapidly becoming a research hotspot and a new direction for industrialization in the photovoltaic field due to their high efficiency, low cost, and material diversity.

In perovskite cell production, film uniformity plays a decisive role in cell performance and is a key factor in industry development. A perovskite film of uneven thickness with pinholes can greatly reduce the battery's photoelectric conversion efficiency, seriously affecting its stability and service life.

Recently, a major research achievement published in the top international journal Science has brought breakthrough progress to the global photovoltaic industry — a new type of dual radical self-assembling molecular material developed by the research team of Qin Chuanjiang

With the rapid development of perovskite technology, the precision and adaptability of coating equipment directly affect R&D efficiency and mass production results.
