The Japanese industrial technology supplier is shipping coating tools for perovskite solar panels with dimensions up to 1,000 mm x 2,000 mm. The company will soon also support 2,400 mm × 1,200 mm sizes.
Japanese industrial technology supplier Toray Engineering offers coating tools to support perovskite panels with dimensions up to 1,000 mm x 2,000 mm.
The slot nozzle coating technology, also called slot die coating, enables fast, precise and uniform perovskite thin film coatings for a range of panel sizes including 1,200mm x 600mm and 1,000mm x 2,000mm, the company said.
Toray Engineering will soon support even larger sizes. “The 2,400mm x 1,200mm size will ship at the end of this year,” said Katsumi Araki, technical sales account manager of Toray Engineering. pv magazine.
The equipment is intended for large-scale production, usually for an inline process. “Nowadays we concentrate on production lines from sheet to sheet. This is because there is a large market for applications using glass and there is great potential,” said Araki.
The tools feature low viscosity fluid handling up to 20 coating speeds (cp) and a coating thickness of 1 μm. The CP is typically 50 mm/sec. Optional extensions include vacuum chambers (VCD), an air knife for accelerated drying and glass transfer robots.
The company has a customer for one of its large perovskite solar coaters, but the company name is not disclosed other than to say the customer is in Asia. Araki said one customer is currently shipping perovskite panels.
Traditionally serving the liquid crystal display (LCD) and organic light emitting diode (OLED) industries, Toray Engineering’s largest coating tools support panels measuring 3,000mm x 3,000mm.
Toray Engineering belongs to Toray Industries, a diversified Japanese company active in the fields of organic synthetic chemistry, polymer chemistry and biochemistry.
