Have you ever wondered: the sun never works overtime, but humans need electricity 24 hours a day?

The Slot-Die Coating process for perovskite solar cells is a key technology for efficient, scalable film fabrication.

Perovskite photovoltaic technology is at a critical stage from the laboratory to industrialization. Its unique "thin-film" manufacturing process has given rise to and relies on a core production equipment system completely different from crystalline silicon photovoltaics.

With the development of emerging fields such as wearable electronics and integrated building photovoltaics, flexible perovskite solar cells show tremendous application potential due to their bendability, lightweight, and windable properties.

The air flotation platform plays a crucial role in the mass-produced perovskite coating process. Its unique non-contact suspension technology not only improves coating uniformity and stability but also significantly enhances production efficiency and product quality.

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
