In the third interview of a series, pv magazine spoke to Prof. Arvind Shah of École polytechnique fédérale de Lausanne and Associate Prof. Alessandro Romeo from the University of Verona about the challenges and opportunities of cadmium telluride (CdTe) PV tech. They said there is still potential to ramp up efficiency and cut costs, and claimed that the toxicity of cadmium should not be seen as a serious concern.
U.K. researchers have developed a flexible thin-film cadmium telluride (CdTe) solar cell for use in ultra-thin glass for space applications.
German PV production equipment provider Singulus will supply the vacuum coating systems for the new production. The Chinese conglomerate currently operates CIGS panel production facilities at four different locations in China.
The US cadmium telluride thin-film module maker said its Series 6 CuRe panels are able to retain 92% of its performance at the end of the 30-year warranty. The improved stability of the product was achieved by eliminating copper and placing Group V elements such as antimony or arsenic onto the tellurium crystal sites.
US researchers have unvelied a new manufacturing process to produce cadmium telluride (CdTe) PV panels, which they claim is 45% cheaper than current industry standards. The technique relies on the use of a high-pressure Bridgman furnace, which is a kind of industrial furnace utilized for crystal growth and directional solidification of polycrystalline ingots.
Calyxo, a German cadmium telluride solar module manufacturer, has filed for insolvency for the second time, despite the recent emergence of new prospective investors. Meanwhile, Crystalsol – an Austrian flexible solar panel maker – has also initiated insolvency proceedings, due to losses of roughly €7 million.
