Solar Power

The new devices feature efficiencies ranging from 20.7-21%. The panels are said to be compatible with a wide range of slates and tiles, include special fixings for different batten thicknesses, and achieve the highest fire rating and wind resistance without modifications to the roof.

The new Novotegra GmbH unit will bundle all activities related to the group’s PV mounting structure business.

Off-grid PV has become a much more viable solution than diesel power generators to bring electricity to Russia’s remotest regions. Furthermore, solar-plus-storage is able to deliver with no interruption 24 hours per day and seven days per week, while fuel availability means diesel power can only ensure between four and seven hours per day.

U.S. researchers are developing thin-film PV technologies to create lightweight solar sheets to support communication satellites and wirelessly transmit power to Earth-based receivers. A space-based solar array could include tens of millions of sheets, with a capacity of up to 800 MW.

A refinery of Italian oil product provider Saras will host a large scale electrolyzer that will produce hydrogen to be used as a raw material in the refinery itself. The green energy production will be set up by Italian energy company Enel.

Sony lab and LF Energy are developing a new approach to enable peer-to-peer microgrid energy trading, so remote communities can store and distribute energy without connecting to large-scale power stations or distribution grids.

The Ranger Uranium Mine ceased production in Australia’s Kakadu National Park in January, following years of financial losses. Now, as part of a multimillion dollar rejuvenation of the park, there are plans to develop a solar and battery storage hybrid project near the town of Jabiru.

The new interdigitated back-contact module comes with power outputs ranging from 370 to 380 W and is the most powerful panel produced by the company to date.

South Korean scientists have produced a solar cell based on antimony selenoiodide, with a 4.1% efficiency, a short-circuit current density of 14.8 mA cm2, an open-circuit voltage of 473.0 mV, and a fill factor of 58.7%. They claim the cell exhibits excellent stability in humid conditions.

In various forms, quantum dot technology has attracted plenty of attention among PV researchers recently. And as efficiencies have crept past the 15% mark, the community is beginning to look at other factors limiting the viability of quantum dot solar cells in a commercial setting. Scientists in Germany examined the degradation mechanisms affecting different quantum dot materials; and suggest a standardization of stability testing to enable comparability of results.
