Cross-Sectional Transport Imaging in a Multijunction Solar Cell
IEEE Journal of Photovoltaics(2017)
摘要
We combine a highly localized electron-beam point source excitation to generate excess free carriers with the spatial resolution of optical near-field imaging to map recombination in a cross-sectioned multijunction (Ga0.5In0.5P/GaIn0.01As/Ge) solar cell. By mapping the spatial variations in emission of light for fixed generation (as opposed to traditional cathodoluminescence (CL), which maps integ...
