NOVELTY - The method of an enhanced amorphous diamond like carbon (DLC) multi-layer doping growth, comprises forming first and second DLC layers for creating connected PIN junctions (120) from a first junction to a last junction, varying a sp2/sp3 ratio of the p-type and n-type layers and doping the layers with silver to enhance electron mobility in PIN junctions, which have p-type, n-type and intrinsic layers, and connecting the first and second DLC layers between electrodes at the first and second sides to create a device having optimized spectral response, which is oriented to a light source (35).    USE - The method is useful for an amorphous diamond like carbon multi-layer doping growth (claimed).    ADVANTAGE - The method ensures economical growth of the diamond like carbon layer with high hardness, low friction coefficient, chemical inertness, infrared optical transparency, high electrical resistivity and smoothness.    DETAILED DESCRIPTION - The method for an enhanced amorphous diamond like carbon (DLC) multi-layer doping growth, comprises forming first and second DLC layers for creating connected PIN junctions (120) from a first junction to a last junction, varying a sp2/sp3 ratio of the p-type and n-type layers and doping the layers with silver to enhance electron mobility in PIN junctions, which have p-type, n-type and intrinsic layers, and connecting the first and second DLC layers between electrodes at the first and second sides to create a device having optimized spectral response, which is oriented to a light source (35). The sp2/sp3 ratio varies from 4.0 ev in DLC layers, which are closest to the light source to 0.60 ev in DLC layers, which are furthest from the light source. The doped DLC layers are performed to yield a controlled photovoltaic response from first to last junctions. The optimized spectral response yields energy efficiency of the device, and comprises focusing incident light onto the device. The device is a photovoltaic cell, a part of an integrated circuit or a solar cell. An INDEPENDENT CLAIM is included for a DLC multi-layer device.
