Improvement in pinpin device architectures for imaging applications

In this paper we present results on the optimization of device architectures for color and imaging applications, using a device with a TCO/pinpi'n'/TCO configuration. A set of different devices with different intrinsic back layers (i') are analysed. The effect of the applied voltage on the color selectivity is discussed. Results show that the spectral response curves demonstrate rather good separation between the red, green and blue basic colors. Combining the information obtained under positive and negative applied bias a color image is acquired without color filters or pixel architecture. A low level image processing algorithm is used for the color image reconstruction.
