Switzerland-based Energy Pier has developed a new concept for hybrid-wind solar projects located along highways. The proposed solution combines a rooftop PV system with small scale wind generators that are installed on both sides of the supporting pillars of the system.

Scientists in Germany developed a new process for manufacturing battery electrodes, that they say could be both more cost effective and environmentally friendly compared to current technologies. The technique could be applied to a range of different battery materials/chemistries and its creators say they are in discussion with a number of battery cell manufacturers regarding pilot production.

A Dutch research group has shown that south-oriented solar parks offer better environmental conditions for soil and vegetation than east-west oriented facilities. According to their findings, a distance between panel rows of at least 1.5 times panel height is crucial to favor ideal plant growth and soil functioning.

Scientists in Switzerland found that perovskites can be used to detect thermal neutrons emitted by radioactive devices. Taking advantage of several properties that also make the materials attractive for solar cell applications, the group was able to fabricate a novel device that could have various practical applications, including in energy generation.

US scientists claim to have created a crossover-free, high-voltage, non-aqueous hybrid flow battery with a novel chemistry for the solid sodium anode. The device has shown a high working voltage of around 2.6 V and a coulombic efficiency of 95.0%.

The portable module has a foldable design with a four-panel structure and a power output of 100 W. It also incorporates a Suncast module that indicates the best height and tilt angle it must have to ensure optimal yield.

Called SolFlex, the frameless panel is based on 22%-efficient solar cells and is designed for high, one-sided heat load. The standard product measures 100x100x2.9cm, weighs in at 3.4kg, and has a power output of 170 W.

Feeding solar electricity directly from its own panels into overhead lines, on a fully-electrified rail network, would be more cost-effective for the state-owned company than buying that green power from the grid, according to a new study.

German solar company Polarstern sees many performance-enhancing effects when photovoltaic systems are combined with green roofs. These are provided by cooling, dust absorption and reflective behavior, which are favored by the plants on the roof.

Scientists in the UK have explained the mechanism behind chlorine used to boost the efficiency of cadmium telluride thin-film solar cells. With new understanding of the chemical processes at work in the manufacturing process, the group hopes to be able to push for cell efficiencies beyond 25%.
