CdTe Solar Cells
Record CdTe device efficiency has recently
surpassed 20%, and it is the leading thin film photovoltaic technology in terms of commercial installation. However,
additional improvements in efficiency, reliability and cost are required to keep pace with crystalline silicon.
The Wolden group in collaboration with NREK is developing high quality CdTe with improved carrier
lifetime, density, and open circuit voltage. Specific projects focus on the development of ternary
alloys, group V dopants, and alternative window layers. The work is conducted primarily at NREL under
the leadership of Dr. Matt Reese. This work is supported by the National Renewable Energy
Laboratory under Contract UGA-0-041025-214.
