ISET ships non-vacuum CIGS modules
The company reverses industry trends by exporting PV modules to Asia.
International Solar Electric Technology, Inc. (ISET), a manufacturer of printed thin-film CIGS solar panels, has shipped full-sized modules to initial customers in South Korea from its pilot production facility in Los Angeles. Initial products were designed and assembled to meet the specifications of distributed power markets as ISET targets growth in an underserved industry segment.
The CIGS modules will supply off-grid electricity for green LED lighting applications in agricultural, industrial, and transportation markets. ISET raised just under $18 million to develop a pilot facility in Southern California capable of manufacturing CIGS modules from bare glass to final module assembly.
ISET says it is the first PV company to ship monolithically-integrated CIGS products based on a printed ink process. ISET’s CEO and President Vijay K. Kapur identified this milestone as “the product of thinking globally and competitively,” pointing out that “global competition has pushed prices to a level which we had anticipated from the start. For that reason, I am extremely proud that we have begun to export American-made PV products based on ISET’s manufacturing platform which can be truly cost competitive.”
The company’s first shipments follow closely upon recent announcements of efficiency and yield milestones in preparation for expansion to volume manufacturing.
Osram LEDs combine maximum flexibility with minimal size
The firm says its latest Oslon Square LEDs make even better use of light.
Osram Opto Semiconductors new LED, the Oslon Square, opens up a wide range of possible uses, including designer luminaires for the home or office, retrofits and street lights.
The LED is available in many different versions with different colour temperatures. It can be operated with different currents, making it extremely versatile. Its reflective package makes even better use of the light and increases system efficiency in all versions.
High efficiency: the reflective package of Oslon Square makes use even of the light emitted at the side between the chip and the lens.
The Oslon Square can be used in a wide range of applications, from cool designer luminaires to bright street lights. And there is no need to change the manufacturing process for the lamps because this new LED has all the right credentials for widespread use – it is small, powerful and capable of operating on different currents. This one LED can therefore be used for manufacturing different products for different target markets.
Like the Oslon SSL, the Square measures only 3 x 3 mm, has a low thermal resistance of 4 to 3.8 K/W and is accommodated in a robust package which is suitable for outdoor use. Particularly worthy of mention is the high system efficiency that can be achieved with this versatile LED. The LED chip is enclosed by a reflective package that reflects light emitted at the side or at the back so that this light is
