Abstract

Concentrating photovoltaics is an attractive route for achieving high power output with thin film solar cells, using low-cost optics. In this work, the performance of CdTe:As thin film solar cells on two different transparent conducting oxide (TCO)-coated substrates is investigated and compared unde...
