EPIR Technologies Inc. says it has repeatedly fabricated high-efficiency polycrystalline cadmium telluride (CdTe) solar cells on commercial glass substrates. The company has been working with a team of scientists from the National Renewable Energy Laboratory (NREL), notes Siva Sivananthan, founder and CEO of EPIR Technologies.
According to Chollada Gilmore, EPIR's CdTe solar cell technical lead, the cell was officially verified by NREL at 15.2 % efficiency. The high efficiency was driven by a fill factor of 77.6%, and the cells were fabricated using inexpensive commercial TEC-series glass substrates rather than technical-grade glass.
