DuPont Photovoltaic Fluoromaterials signs Technology Licensing Agreement with Toppan

Agreement to boost production of backsheet containing Tedlar® for growing photovoltaic market

DuPont Photovoltaic Fluoromaterials (PVFM) announced it has developed a proprietary technology to produce backsheet containing DuPont™ Tedlar® polyvinyl fluoride (PVF) polymer in a single step, and has signed a Technology Licensing Agreement with Toppan Inc. Printing Co. Ltd, located in Tokyo, Japan, to commercialise backsheet for photovoltaic (PV) modules using this new technology.

DuPont™ Tedlar® polyvinyl fluoride films are in high demand for use in durable, weatherable backsheets for photovoltaic modules.

This technical and business development is in line with the PVFM strategic intent to significantly increase the availability of Tedlar® films and backsheet for the fast growing PV market. DuPont expects commercialisation of the new backsheet product from Toppan using this technology in 2010.

“This collaboration combines DuPont’s proprietary technology for Tedlar® polymer in backsheets, with Toppan’s unique coating capability,” said Kelly Kolliopoulos, global business manager, Tedlar®. “We view the new backsheet technology as complementary to our continuing activities to increase the supply of Tedlar® films in order to meet the industry’s growth and demand for Tedlar®. Increasing capacity continues to be the top priority for this business, and we will continue to communicate further developments related to Tedlar® film expansion planning in the future.”

This technology licence follows on the heels of recent manufacturing expansions for Tedlar® polymer and newest Tedlar® PV2100 series films, in addition to incremental expansions of its capacity for Tedlar® PV2000 series film. The capacity for Tedlar® PV2100 films has increased by 20 fold in the last year. DuPont continues planning for future capacity expansions for the Tedlar® monomer, polymer and films it produces.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
