A German research group has used spectroscopic methods based on terahertz or microwave radiation and has discovered that they might help with more precise assessments of the characteristics and performance of solar cells. Their proposed approach purportedly enables the evaluation of maximum possible efficiency levels for emerging materials such as perovskites in solar cells.

Researchers in Canada have conducted a series of simulations to understand how spectrum splitters may raise the efficiency of two-terminal tandem solar cells and have found that efficiency gains may be of up to 6%. The proposed cell configuration was also found to be economically competitive.

A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.

Bird Control Group’s autonomous laser system reduces bird populations in specific areas by more than 70%. In many cases, bird activity has been reduced by more than 99%.

Researchers from Australia’s Monash University have created a new generation of lithium-sulfur batteries to provide a cheaper, cleaner and faster-charging energy storage solution that outlasts lithium-ion alternatives and is rechargeable hundreds of times without failing.

Developed by Swedish manufacturer Polestar, the hard-top convertible incorporates a drone that can be launched from its dock behind the rear seats whilst driving to capture footage of the journey.

Panasonic has also unveiled plans for two new production facilities for its large-format cylindrical battery cells.

Mitrex solar facades are being installed on a 7000 square feet area on a building in Canada, producing an estimated 90,000 kWh of power annually.

In other news, Belgian company Tree Energy Solutions (TES) is accelerating plans to develop the German port of Wilhelmshaven into a “world-scale” hub for importing green gas, and German engineering company MAN Energy Solutions will invest up to €500 million in its hydrogen-focused subsidiary H-TEC Systems.

A group of researchers in the United Kingdom is developing a modular, multi-vector energy system that can be installed into new homes and retrofitted into existing buildings to provide seasonal heat storage. In the proposed system configuration, a rooftop solar array would be used to power a heat pump or another electrical heating element, which in turn produces the heat to be stored by thermal devices.

Megasol said the solar module relies on new back-contact technology that is able to reduce internal resistance, ohmic losses and cell spacing.
