3D Lifetime Tomography Reveals How CdCl2 Improves Recombination Throughout CdTe Solar Cells

Using two‐photon tomography, carrier lifetimes are mapped in polycrystalline CdTe photovoltaic devices. These 3D maps probe subsurface carrier dynamics that are inaccessible with traditional optical techniques. They reveal that CdCl2 treatment of CdTe solar cells suppresses nonradiative recombinatio...
