Effective I-V Measurement Techniques for Busbarless and …
Abstract: Conventional I-V testing of solar cells involves probe bars with voltage sense points and current sourcing points on the cell''s front busbars. However, this approach is not suitable for busbarless solar cells and multi-busbar (example: 12 to 18 narrow busbars) solar cells. This work introduces three measurement probe configurations for the I-V testing of …

Dark IV Measurements
Since solar cells convert light to electricity it might seem odd to measure the photovoltaic cells in the dark. However, dark IV measurements are invaluable in examining the diode properties. Under illumination, small fluctuations in the light intensity add considerable noise to the system making it difficult to reproduce.
