Perovskite photovoltaic cells - Ultrasonic precision spraying

Perovskite photovoltaic cells -- Precision spraying -- YMUS ultrasonic spraying

Although perovskite is a promising alternative to crystalline silicon cells, new manufacturing processes are needed to make it commercially viable. To help fill this gap, YMUS has researched and developed an ultrasonic precision spray coating device to enable mass production of more complex perovskite solar cell designs. Perovskites are expected to be used in the next generation of solar cells because they are more efficient than silicon at absorbing light and converting it into energy and are cheaper to produce. Perovskite can even be sprayed onto glass to create Windows that generate electricity.

YMUS Ultrasonic spraying applies the solution layer by layer to the substrate, and the thickness and rate of deposition of each layer is precisely controlled during the deposition of perovskite.

A better way to paint

One of the advantages of perovskites is that they are solution-treatable, meaning that solar cells are made by drying liquid perovskite into a solid at low temperatures. The manufacturing process is much easier than making traditional silicon solar cells, which require very high temperatures and cutting solid materials into wafers. The solution method commonly used to prepare perovskite does not allow for multilayer designs because the upper layer tends to dissolve the already dried lower layer. To overcome this challenge, the researchers turned to a process called sequential jet deposition, in which tiny droplets of material are applied to a surface.
