EPIR Technologies, NREL Achieve Advancement in Polycrystalline CdTE Solar Cells

EPIR Technologies declared that it has often constructed high power generating polycrystalline cadmium telluride (CdTE) solar cells on commercial grade glass substrates.

The company has been closely partnering with a group of scientists from National Renewable Energy Laboratory (NREL), on the project and has formulated a CdTe solar cell with a top efficiency of 15.2%. According to Dr. Siva Sivananthan, CEO of EPIR Technologies, the cell efficiency was achieved in a short period of time by mixing the expertise of EPIR in CdTe materials and the know-how of NREL in CdTe solar cell device technology.

Dr. Chollada Gilmore, Technical Lead for the CdTe Solar Cell at EPIR, said that the power efficiency of the solar cell was formally confirmed by NREL as 15.2%. The higher efficiency was made possible by a fill factor of 77.6%, which is said to be one of the top rated fill factor values ever registered for the type of solar cell utilized. He added that the results are very important because the solar cells were produced with cheap commercial type TEC-Series glass substrates instead of technical-grade glass as used in champion  cell fabrication.
