Non-Contact measurement of characteristics of p-n junctions includes illuminating an illumination area of a surface of a p-n junction with light, measuring a first junction photovoltage (JPV) signal from a first area of the p-n junction with a first electrode, measuring a second JPV signal from a second area with a second electrode, measuring a third JPV signal from a third area with a reference electrode, and determining a sheet resistance of the p-n junction top layer with a corrected first JPV signal, a corrected second JPV signal, a corrected first calibration JPV signal, a corrected second calibration JPV signal or the known sheet resistance of the calibration p-n junction. |
