A Swedish-Chinese research team has developed an organic cell said to be ideal for wide use in daily life to power internet of things-enabled devices. The cell could be used to power sensors that detect and measure moisture, particle concentrations, temperature and other parameters indoors.

Most of the generation capacity – around 63 MW – was deployed in the emirate over the last 14 months.

The future benefits of technology such as smart meters and the associated aggregation of small scale generation are not being adequately rewarded, support for solar and wind is being cut off and parliament is fixated solely on one issue.

The obligation will be applied annually from 2022. The clean electricity required will have to be bought through power purchase contracts of at least 10 years’ duration.

Credibility comes not just from offering products that generate clean electricity, but also from the way in which those products are manufactured, says SMA Solar Technology CEO Jürgen Reinert. Here, transparency and sustainability are key. That’s why one of the world’s largest PV inverter producers has partnered with pv magazine’s UP sustainability initiative. In the following Q&A, Reinert lays out what SMA is doing to step UP its green game.

Researchers from the Ulsan Institute of Science and Technology have demonstrated a new method of fabricating perovskite-on-silicon tandem devices, using a transparent conductive adhesive to combine the two cells. The scientists have developed devices with demonstrated efficiencies of 19.4%, and propose strategies to bring that above 24% using existing technology.

Grid expert Andrea Mansoldo tells pv magazine how energy markets based on solar and storage are feasible as an alternative to costly grid infrastructure work. He says around 6 GWh of battery capacity may be a good alternative to building 1000km of power line or an AC 750 kV high-voltage line.

EuPD Research has calculated what needs to be done to replace the nuclear and coal generation to be phased out in Germany. Accelerated expansion of PV appears the best short-term option. However, storage capacity will need to increase 30-fold by 2040 so solar can become the main pillar of the country’s energy system.

Carbon clusters of a few nanometers in size could be responsible for the defects affecting the thermal stability of SiCs. The defective carbon accumulations arise during the oxidation of silicon carbide to silicon dioxide under high temperatures.

This week, pv magazine headed to Marseille for the 36th edition of the EU PVSEC conference and exhibition. During the week-long show, leading universities and research institutes presented their latest results to the industry and public. As the conference heads into its final afternoon, we’ve put together five key takeaways from this year’s event.
