CdTe

An Indo-Malay research group has sought to define the best conditions for developing large scale solar projects at airports. The researchers provided insight on glare analysis as well as design and performance.

Superior hydrodynamic properties, more robustness in high seas and a much reduced logistics requirement support the case for thin-film over crystalline silicon, pontoon-mounted alternatives, according to an Indo-Italian research group.

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.

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.

Getting on for 300 international exhibitors are attending the Solar Bangladesh Expo in Dhaka which opened today and runs until Saturday. pv magazine’s Syful Islam is walking the floors and hearing optimistic messages.

The thin film PV maker reported solid year-end 2018 results, with future bookings extending out four years and the fourth of five Series 6 factories already online.

A novel method developed in Tokyo, Japan, allows a nitride crystal to grow, which can function as both an n- and p-type conductor. The material can replace cadmium-telluride (CdTe) in thin films, and make such solar cells more environmentally friendly, while enabling greater efficiencies, the researchers claim.

TS Group GmbH has taken over the entire business of the insolvent PV manufacturer. All of the German company’s 130 workers will continue to be employed. Production of cadmium telluride thin film PV modules at the Bitterfeld-Wolfen site, near Berlin, will continue.
