dc.description.abstractSince 2015, commercial sample holders have been available that enable cathodoluminescence imaging of semiconductors in the TEM. Despite this, issues with low signal have meant that high resolution TEM-CL imaging has so far not been achieved on a solar cell. Here, we use xenon ion milling and cryogenic sample cooling to boost signal from the TEM foil, enabling high resolution CL imaging of a bilayer CdSeTe/CdTe solar cell for the first time. The results show that selenium has a passivation effect on grain boundaries in alloyed CdSeTe material, helping to explain the superior performance of CdSeTe solar cells.en_US
