Scientists from the University of Groningen have discovered a tin-based perovskite material in which electrons retain high energy levels for much longer than previously. This discovery could allow for the creation of very high efficiency perovskite cells, by eliminating a large portion of energy loss through heat.
Contrary to common belief, holes in perovskite films may not always negatively affect the performance of perovskite-based solar cells, according to recent research from the Helmholtz Zentrum Berlin (HZB).
The renewable energy subsidiary of German power company, RWE aims to build more solar power projects in the Netherlands, Germany and the U.S., and has signed a new agreement for 1 GW of PV in Canada.
A 250 kW PV system will provide around 4% of the bridge’s energy needs. The project may be expanded to 700 kW.
Negotiators of the three German parties have agreed on a common preliminary paper. They also agreed on additional tenders for large-scale solar and wind power projects, with a volume of 4 GW in the years 2019 and 2020.
Researchers have developed and designed a new algae-powered fuel cell that is five times more efficient than existing plant and algal models, as well as having the potential of being more cost-effective to produce and more practical to use.
According to provisional figures released by Swissolar, solar demand remained stable in the country last year. Looking ahead, the association expects another 300 MW to be deployed this year.
These projects would be developed without direct public incentives and would sell power to the spot market – an option still considered unviable by the local renewable energy sector – or through private PPAs. Meanwhile, local power provider, Axpo Iberia has agreed to buy electricity from a 28 MW solar facility planned in southern Portugal under a 10-year PPA.
Collaboration between the U.S. energy firm and the German power electronics giant officially licensed on January 1, as details of a massive 100 MW/400 MWh lithium-ion battery storage project in California were announced.
The solar park was built on an area previously used for logging and which has been unused for several years.
