Abstract
A color sensor produced in accordance with the present invention comprises a colorless and transparent substrate; at least one color filter disposed on a main surface of the substrate; a colorless and transparent front electrode layer of transparent conductive oxides (TCO) formed on the opposite main surface of the substrate, corresponding to each of the filters; a semiconductor layer formed on the front electrode layer, wherein the interface between the front electrode layer and semiconductor layer is roughened to have a periodic unevenness thereby to decrease the reflectance of visible incident light at the interface; and a back electrode layer formed on the semiconductor layer.
