Comments: With nearly $38 billion in sales in 2011, DuPont prides itself as a science company that develops a wide range of solutions for countless markets, including inkjet and printed electronics.
In terms of the digital ink market, DuPont has been the leading supplier of OEM inks for desktop printers, as well as digital textile inks with its Artistri system.
The printed electronics market has tremendous potential, and DuPont has made strong inroads in the solar market, with more than $1 billion in sales in that segment. DuPont Microcircuit Materials (MCM), part of DuPont Electronics & Communications, has been in the forefront in the conductive ink field, developing functional inks and metallization pastes for photovoltaics (PV), organic light emitting diodes (OLED), biomedical sensors, flexible displays, electroluminescent (EL) lighting, membrane touch switches, printed batteries, RFID antennae and other printed electronic applications.
DuPont’s inks are suitable for roll-to-roll screen printing, flexo, gravure, photo-imaging, pad printing, inkjet and other processing techniques.
For example, the company launched DuPont 5064H in November 2011. DuPont 5064H is a highly conductive silver paste that can be screen printed onto a variety of substrates. The company also offers its Solamet line of photovoltaic metallization pastes, most recently launching Solamet PV414, designed for rotary screen printing to enable high speed roll-to-roll processing of thin and flexible solar cells and modules.
In July 2011, DuPont acquired Innovalight, Inc., a Sunnyvale, CA-based specialist in advanced silicon inks and process technologies that increase the efficiency of crystalline silicon solar cells.
“Innovalight has very exciting technology that improves cell efficiency and DuPont can help expedite its adoption,” said David B. Miller, president – DuPont Electronics & Communications.“DuPont and Innovalight share a commitment to innovation in materials that have a common purpose – to make solar energy more efficient and more affordable.”
