Electric field distribution of solar cells
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
We report on a direct measurement of the spatial distribution of electrical potential on cross sections of hydrogenated amorphous silicon (a-Si:H) n–i–p solar cells using scanning Kelvin probe microscopy. We found that most voltage has dropped near the p/i interface up to ∼500 nm into the i-layer, but that the voltage flattens out near the n/i …
