According to The Nikkei Business Daily (Tuesday, Feb 5 '08 edition) National Institute of Advanced Industrial Science and Technology and Rohm Co. have jointly developed a new image sensor by fabricating a thin film of copper indium gallium di-selenide (CIGS) above the silicon substrate. The inventors were able to overcome the current leakage problem associated with CIGS. This sensor is more than six times as sensitive as a conventional silicon-based device and is also capable of detecting light across a broader spectrum, from visible light to near infrared light (up to a wavelength of 1,300 nanometers). 90% of the surface of this sensor is capable of detecting light which is triple the normal amount.
According to Nikkei "this combination of features can boost the shutter speed of digital cameras and provide the kind of nighttime vision useable for monitoring cameras and car-mounted safety systems".
