An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.

A Swiss start-up has created a containerised movable PV system that is designed to be easily relocated to allow the use of solar energy in locations where a fixed installation is not an option. The solution is based on a racking technology which can include two racks able to host up to 30 solar panels.

Hydrogen and hydrogen-based fuels will not be able to move forward fast enough to replace fossil fuels and tackle climate change, according to a German-Swiss research team that claims direct electrification alternatives are cheaper and easier to implement. The scientists cite too-high prices, short-term scarcity and long-term uncertainty, as the main reasons for their skepticism, which has caused a stir in academic circles.

Oil and metals trader will join forces with Australian investment group IFM to launch the new entity, which will develop solar, wind and energy storage projects – some of them supplying clean energy to Trafigura operations – as well as making acquisitions.

Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² flexible thin-film cell intended for building-integrated PV application. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.

A consortium of European research institutes has received €10.6 million in EU funding to establish pilot production of a high efficiency module concept developed by Swiss startup Insolight. The module combines high efficiency multijunction cells with a solar concentrator lens and has previously demonstrated 29% efficiency.

Some 377 households and a retirement home are participating in a pilot project. In the first two weeks of this month, solar power generators sold 82% of their electricity within the neighborhood. The goal of the one-year test run is to develop a viable concept for the trading of solar power.
