Development of cathodoluminescence spectrum imaging characterization of CdTe solar cells
To make renewable electricity cost-competitive with fossil fuel electricity, we must continue to improve photovoltaic (PV) and other renewable technologies. CdTe solar cells are a commercialized PV technology that is a leader in terms of both efficiency and cost. As CdTe solar cells approach theoretical or practical efficiency limits, we need robust characterization tools and data analysis to help guide empirical device development. Cathodoluminescence (CL) is a scanning electron microscope-based characterization technique that can probe the opto-electronic properties of solar cells with high ...
