Photovoltaic Technology - CdTe Thin Film PV
CdTe thin film PV is one of the main thin film PV technologies being commercialized. CdTe has the advantage of a direct bandgap which matches well with the solar spectrum, a high absorption coefficient, the ability to be doped both n-type and p-type, and processes that can work for low cost, large scale manufacturing.
The main areas for improvement of CdTe thin film PV are the cell and module efficiencies. Materials characterization using surface analysis methods can be used to support R&D of efficiency improvements.
The schematic of the CdTe Thin Film PV device structure (below) illustrates some of the ways surface analysis can help.
