An international team of scientists working with polymer-fullerene solar cells has developed a process of fluorination, which demonstrated a significant boost in cell efficiency. According to Moscow Institute of Physics and Technology, the discovery could assist the development of new thin film solar materials.

The International Energy Agency’s latest study of global energy investment paints another rosy picture for solar – even as the authors warn of missed sustainable growth targets – but the report covers last year, and notes China’s policy about-turn could blow a cold wind through PV.

Following the claim filed in June, SolarEdge now alleges Huawei has infringed two more of its patents. With its HD-wave inverter topology the subject of the first lawsuit, the Israeli manufacturer now says its Chinese rival also copied its power optimizer technology.

Two months after announcing its intention to turn to renewables, the Spanish oil giant has for the first time formed a technological tie-up that integrates a partner into the company’s value chain.

A team of researchers from the University of Exeter has demonstrated a technique which creates ‘charge funnels’ within certain semiconductor materials. The researchers state that the technique could eventually lead to the development of PV cells with better than 60% efficiency.

Spain, Portugal, France and the European Commission have signed a deal to increase the capacity of the energy interconnection between the Iberian Peninsula and Europe. Currently, the interconnection capacity is 6,000 MW and, thus, far from the 15% goal set in 2015.

The Chinese state-owned State Grid Corporation of China has been attempting to acquire a 20% stake in German transmission system operator, 50Hertz for some time now. After the intervention of Germany’s Federal Government, however, this share will now go to domestic development bank, KfW.

Oil and gas company Total has announced it will work alongside Shanghai-based NIO – the world’s inaugural Formula E champion – to develop products for a potentially huge electric vehicle marketplace in the populous Asian nation.

Belgian research institute, Imec has announced the achievement of 27.1% efficiency on a perovskite/silicon tandem cell, providing further evidence of the technology’s potential to provide a low cost efficiency boost to existing PV technology.

The storage system supplier is providing its technology to the Isles of Scilly as part of an ERDF-funded project to meet the remote islands’ energy demands more cheaply and cleanly. Until now islanders used fossil fuels and electricity from mainland Britain at high tariffs, prompting energy poverty for many.
