cadmium telluride

The proposed model is said to perform better at energy prediction than software tools such as PVWatts, PVSyst or RetScreen. The approach was validated on two 5 MW PV plants in the same district of the Indian state of Rajasthan.

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.

A study has considered the best mathematical models for predicting solar module performance under varying conditions.

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.

Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.

A new study conducted by an international team of scientists from leading institutions in the U.K. and the United States provides an explanation as to how the addition of selenide can greatly improve the efficiency of cadmium telluride solar cells. Explaining the performance boost will provide researchers with a route to explore further efficiency improvements, pushing the material’s cost even lower.
