“…The FWHMs of all peaks were all below 150 nm and were, therefore, considered to be "narrow" [141,142]. Further work highlighted that instead of the previous structure, it was more advantageous to employ a sequence of the type glass/ TCO1/p'i'ni'p'/TCO2/p'in/metal (Al) [142,143]. Subsequent more substantial optimization was carried out for the entire device, and yielded thicknesses of 10, 30, 60, 200, 10, 10, 370, and 20 nm, respectively, for all semiconductor layers in this latter structure.…”

This chapter intends to provide an introduction to and a very brief summary of the principal categories of color sensors and of their applications, both relatively little known to the general public.First, an introduction describes the background of the topic(s) and the overall context. The main differences between two major but complementary techniques, colorimetry and spectrometry, will be presented here, as well as a quick summary of the scientific, technical, and industrial applications of color sensing. The second section will summarize the basic operational principles and architectures of color sensors realized in silicon. Although stand-alone detectors will also be described and discussed, the main focus will be on solid-state microsensors which can ideally be monolithically integrated together with signal processing circuits onto the same chip as "smart sensors" or intelligent microsystems. First, sensors realized only in monocrystalline silicon are summarized, followed then by those fabricated in other materials, with amorphous silicon and its alloys as the key players in this latter category.Finally, the chapter ends with the sections devoted to Conclusions and References. This chapter presents only a few of the most relevant aspects related to color sensors and examples of their practical applications. It is, in fact, an extensively abbreviated version of a much more detailed and exhaustive review dedicated to both color sensing and microspectrometry, and which is presently in preparation for future submission to Springer Verlag.

“…Similar to multi junction solar cells are colour detectors, that have been designed to detect two [640,641] or three [642][643][644] colours. A so-called adjustable threshold colour detector (ATCD) consists of an a-Si:H/a-SiC:H p-i-n-i-p-i-n stack [642].…”

A novel sensor concept for the detection of the fundamental components of visible light has been developed. The multichannel sensors (3-, 4-and 6-channel detectors) based on three and four stacked amorphous thin film detectors are color moire or color aliasing free due to their vertical integration. The color separation is performed in the depth of the structure without using optical filters. The developed 3-and 4-channel detectors can be read-out with one shot whereas the color information of the 6-channel detector can be read-out with two shots. The sensors are colorimetrically characterized in order to gain further optimization criteria concerning the improvement of the sensor performance. The presented characterization model facilitates the quantification of color errors with regard to the human perception. Furthermore, the color errors of amorphous thin film sensors are compared with a commercial color CCD camera and a BiCMOS color-sensor.
