The research lab, based in California, has been working with crystal-growing teams at Cornell University and Japan’s Ritsumeikan University. Together they claim their research has led to a single system of alloys incorporating indium, gallium and nitrogen that can convert virtually the full spectrum of sunlight from the near infrared to the far ultraviolet to electrical current. If this is the case, then solar cells made with this alloy will be strong, relatively inexpensive and the most efficient ever produced. (Solarbuzz.com, 18/11/02)New Products Heliotronics, a designer and developer of educational electronics and software for the PV industry, has introduced a new 600V current/voltage transducer. The new transducer addresses the industry trend toward higher voltage PV systems.
