Yolk yesterday won the Aid Innovation challenge at the 2018 AidEX in Brussels. Using solar PV in a fun, novel manner, the Korean social enterprise has addressed major social problems in under-developed countries.

Researchers from the Rice University in Houston, Texas, have unveiled new findings in the field of organic photovoltaics (OPV).

Even in its low ball scenario, the International Energy Agency (IEA) imagines that installed solar PV capacity will overtake that of all other forms of energy apart from gas by 2040. Overall, it presents four scenarios in its 2018 World Energy Outlook, which show a changing energy landscape. While it finds that CO2 levels are, perversely, on the rise, and that many energy efforts in all but the most whimsical of its forecasts are far behind those needed to seriously address global warming, it still imagines coal, oil and gas playing a leading role in our energy mix going forward. It also sees “dramatic” transformation in the electricity sector. Long story short: Read something else if you want to take real climate action. We suggest The Drawdown.

A team of researchers from Germany’s Martin Luther University Halle Wittenberg has developed a new approach to perovskite cell production, which they say could result in better stability and longer lifetimes. The team also made detailed observation of the perovskite’s formation and decay, which could help to inform further research into high performance solar cells.

Companies keen to offset their carbon emissions will be able to purchase renewable energy certificates at Singapore’s first blockchain-powered marketplace, launched by electricity provider SP Group.

In late September, Heraeus launched its Selectively Coated Ribbons (SCR) technology. The product will be rolled out in partnership with ribbon supplier Ulbrich. Delivering a 1.9 W power output boost without any equipment investment and with few process changes, Heraeus’ Toralf Eggert and Ulbrich’s Peter Berghofer claim SCR will make conventional busbars competitive with unwieldy multi-busbars.

Chinese monocrystalline manufacturer Longi Solar Technology has broken its own record for PERC module efficiency, reaching 20.83% in independent testing conducted by TÜV Süd.

The first annual Battery Performance Scorecard has turned up interesting findings, including the fact high temperatures can help or hinder power output – depending on the product, and seemingly in equal measure.

The rise of batteries will attract that headline figure in investment up to 2040, say analysts, as exponential growth in EV ownership, falling stationery system costs and the needs of the world’s grid-poor regions combine to boost lithium-ion technology.

A report published today by U.K.-headquartered energy company Drax says that, for the first time ever, total generation capacity available from renewables has overtaken that of fossil fuels on Britain’s electric grid.
