Abstract: A device and method of manufacture of a:DLC multi-layer doping growth comprising the steps of: forming at least an a:DLC layer in one process over a conventional semiconductor layer, thereby creating a plurality of successively connected PIN/PN junctions, each PIN/PN junction being a photo diode, starting from a first junction and ending in a last junction, respective PIN/PN junctions having p-type, n-type, and intrinsic layers; varying the sp3/sp2 ratio of at least the respective p-type and n-type layers and doping with at least silver to enhance electron mobility in respective PIN junctions; and connecting the plurality of a:DLC layers between electrodes at the first side and the second side to create a device having optimized spectral response to being oriented to a light source. A device comprises at least any kind of PIN/PN junction and an a:DLC PIN/PN junction, and can be connected as an array of devices.
