This DOE SIPS project aims to develop a cadmium telluride (CdTe) passivated emitter rear contact (PERC) solar cell that comprises a patterned aluminum oxide layer and small metal contacts defined on individual grains for greater cell efficiency and power output. PERC cells are designed to capture more light on the back surface of the cell. The team will use current generated by a concentrated stream of electrons to detect any defects in the PERC design and quantify changes in physical parameters, such as the components’ efficiency, using 2- and 3-D numerical models.
