How to Improve Measurement Accuracy of LED and PV Devices with a Common Electrode

Non-metalized contact pads and shared electrodes can undermine the accuracy of solar cell and LED measurements due to high contact resistance, distorting current-voltage (IV) curves and resulting in incorrect maximum-power-point (MPP) and open-voltage circuit (Voc) values. However, solutions exist: metallizing contact pads with gold or silver can reduce resistance issues, and avoiding common electrodes in multi-pixel designs can further enhance measurement accuracy, leading to improved reliability and efficiency in solar cells and LEDs.
