Impact of the Ratio Between Solar Mask Window Width and Electrode Width on the Performance of Light-Generated Current
An efficient process design parameter T, the width ratio of the selective diffusion mask window and the electrode, is presented. The results show that there always exists an optimum T value for different substrate concentrations and doping concentrations to obtain the maximum short-circuit current. As the selective doping concentration is 1×1018~1×1019 cm-3, the optimal T value is 1; when the selective doping concentration is 1 × 1020 cm-3 , the optimal T value is less than 0.5. Increase of the electrode width makes the photocurrent decrease, but it has little effect on the optimal T value. Increasing the selective doping concentration causes decrease of the optimal T value.
