This year’s record-breaking event held in Lisbon, Portugal, included an energy track devoted to renewable sources and technology to address climate change.

The energy transition is becoming ever more apparent among power companies, as was evident at the European Utility Week event last week in Paris, which showcased the hopes and fears of energy companies. Rebranding next year to ‘Enlit’, the organizers aim to reach the whole energy industry.

Toxicologists are struggling to follow the pace at which perovskite solar cells race from laboratory test benches to factory production lines. While researchers continue to assess the health and safety risks stemming from the lead used at the core of these new materials, the startups commercializing them argue that established encapsulation techniques and sound recycling schemes are enough to safety-proof their potentially disruptive technology and offset broader environmental threats.

China General Nuclear Power Group is reportedly preparing to invest almost $2.5 billion into a huge solar project – plus 2 GW of wind turbines – in the autonomous province of Inner Mongolia. Local authorities say the massive project will be complete in 2021.

The new cell is based on a p-type transparent conductor made of carbon nanotube fibers. The device is said to offer 16% more efficiency than rival amorphous cells.

A researcher has proposed a new approach to apply maximum power point tracking techniques to optimize electricity production in wind-solar power projects. The permanent magnetic synchronous generator hybrid model used in the study is based on a multi-input rectifier stage which is said to be able to eradicate current harmonics and eliminate the need for extra input filters.

Researchers at Saudi Arabia’s King Abdullah University of Science and Technology have demonstrated a method they say could improve the stability of perovskite structures. The group found adding an organic dopant served to increase the strength of chemical bonds between organic and inorganic elements of a perovskite.

Scientists led by Moscow’s Skolkovo Institute of Technology have drawn upon several of their recent battery material innovations to create a potassium-ion device. The institute says its development will pave the way for ultrafast and durable, high capacity metal-ion batteries, to supply rising demand for energy storage innovations.

Britain’s renewable energy trade body has published a report examining the state of flexibility market readiness in nine European markets. The result makes for sobering reading for Germany, France and the U.K.

Researchers at Sweden’s Lund University have discovered a mechanism by which iron-based solar cells lose up to 30% of their charge. Understanding how the loss occurs, say the researchers, will be the first step to closing the loophole and developing more efficient solar cells based on the abundant material.
