Renewables reach 65% of net power production in Germany for one week

Renewable energy had a 64.8% share of electricity generation, according to solar research institute Fraunhofer ISE. The achievement was mainly due to strong production from wind facilities.

Hanwha Q-Cells sues Jinko, Longi and REC for patent infringement

The Korean solar manufacturer has lodged a patent infringement lawsuit against Jinko and REC in Germany, and two more against the same companies plus Longi in the U.S. Hanwha Q Cells claims its three rivals have used its patented solar cell passivation technology to increase the performance of their products.

Shell moves to acquire German storage business Sonnen

In May 2018, oil giant Shell invested in German manufacturer Sonnen. Now the 112-year-old company wants to fully acquire the business, subject to Germany’s monopoly authorities. Sonnen said it hopes the deal will accelerate its growth by expanding its market reach and capacity.

Germany installed almost 3 GW of solar in 2018

PV demand grew 68% year-on-year from the level seen in 2017 as Germany’s cumulative installed solar generation capacity reached 45.92 GW.

‘No alternative to 100% renewables’

Transition to a world run entirely on clean energy – together with the implementation of natural climate solutions – is the only way to halt climate change and keep the global temperature rise below 1.5°C, according to another significant study.

German scientists develop new process for stable perovskites

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.
