Cadmium telluride (CdTe) photovoltaics is a photovoltaic (PV) technology based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. Cadmium telluride PV is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi-kilowatt systems. On a lifecycle basis, CdTe PV has t. BackgroundThe dominant PV technology has always been based on wafers. and were early attempts to lower costs. Thin films are based on using thinner layers to absorb an. .
Research in CdTe dates back to the 1950s, because its band gap (~1.5 eV) is almost a perfect match to the distribution of photons in the solar spectrum in terms of conversion to electricity. A simple design evolved in. .
In August 2014 First Solar announced a device with 21.1% . In February 2016, First Solar announced that they had reached a record 22.1% conversion efficiency in their CdTe cells. In 2014, the r.
