The South Korean Inkjet Technology Company is expanding to offer Inkjet printing systems for photovoltaic production of perovskiet. An investment by a business company fund supported by the Japanese Epson Group is expected to help expand the company and increase the applications of its industrial inkjet technology.
Gosan Tech Co., Ltd., a ten-year-old industrial inkjet technology company, which supplies pattern and coating equipment to the display industry for organic light-emitter diode (OLED), has launched a line of inkjet printers for PVOTSon-Son-Son-Sister and Modoskiet-Sskiet-Sskiet-Son-Son-Son-Son-Son-Son-Son-Son-Son-Son-Son-Son.
“Since 2019 we have also focused on developing inkjet processes and equipment specifically to produce perovskite solar cells. As a result, we have supplied inkjet equipment to various bedroom manufacturers in Korea,” said Kwango Kim, CEO of Gosan Tech, said PV -Magazine.
The company’s own inkjet coating and pattern tools, known as the Merak 360-PSC, can be used to manufacture perovskite thin films, hole transport layers (HTL) and electron transport layers (ETL) on stiff glass or flexible PET films. The newest model will relate to perovskiet panels with a large area of 1,100 x 1,300 mm.
“This platform represents an important step further than Pilot scale R&D and emphasizes our willingness for industrial module production,” said Kim.
Support for multi-layer processing within a single tool, the equipment offers low-per-low deposition and the possibility to accurately modulate and control the design, performance and material use of the solar cell, according to GOSAN Tech.
The initial focus on Inkjet systems for OLED displays drove the development of an ink supply system, pressure management technology and simulation technology with reportedly “excellent ink drop uniformity” and a high degree of precision.
While he promotes the equipment side of the company, the company has also developed the capacity to produce its own perovskiet -zonnemodules. “We have currently set up an R&D line on a pilot scale for the production of 370 mm x 470 mm modules, and we expect to produce our first major modules this year,” said Kim.
Regarding the performance of the module, Kim said that the verified data on the efficiency of electricity conversion is expected by the end of the year. In the meantime, the focus is on stability and sustainability.
In order to make the next growth phase possible, Gosan Tech recently received an investment from a business company Fund, supported by the Technology Company Seiko Epson Corporation and Epson X Investment Corporation, which is known as EP-GB LP
According to a statement at the time of the investment announcement, Epson will also deliver Gosan Tech to “reliable and precise printheads that are suitable for industrial applications”, as well as support for business growth through the sales and service site in Korea, Epson Korea Co. Ltd.
“Thanks to our collaboration with Epson, we are able to use Inkjet PrinTheads that have been optimized for the production of perovskiet, so that we can aim both cost effectiveness and high productivity,” Kim said.
There are plans to strengthen the GOSAN Tech product portfolio that goes beyond displays and perovskite Solar PV with biomedical applications, such as drug deposit, tissue technology and diagnostics. Epson also stated that it is developing new printhead markets by forming partnerships to improve the sale and provision of printhead solutions that include peripheral technology.
