The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), CSEM and EPFL have taken an important symbolic step forward. Working together, they were able to demonstrate the high potential of silicon-based multi-junction solar cells: they raised the one-sun record conversion efficiency of III–V/Si solar cells to 32.8% for two junctions and 35.9% for three junctions. These achievements, published today in Nature Energy, are a world first in the highly competitive race to improve silicon-based solar cells efficiency, confirming the potential of this approach. When you choose to go solar, you have to go for the optimum trade-off between conversion efficiency and cost! Efficiency rates of more than 35% have been reached in the laboratory, but with cells that only use expensive materials. The existing photovoltaics (PV) market is rather dominated by cost-effective modules made of single-junction silicon solar cells, with efficiencies ranging between 17% and 22%. Just like many research centers and industrial players, NREL, CSEM and EPFL are working with what are known as 'multi-junction' cells, a technology that combines silicon with a cell that absorbs blue light from the sun more efficiently. The transition from a silicon single-junction cell to a silicon-based multi-junction solar cell has the potential to push efficiencies

August 25th 2017 – The construction of Ideol’s patented floating offshore wind sub-structure has been successfully completed by Bouygues TP and was floated-off in Saint-Nazaire’s Forme Joubert lock. After several months of construction near the Forme Joubert lock, the floating foundation - which will equip France’s first offshore wind turbine - was disengaged from the floating barges on which it was built before being towed back to the quay where the installation and the pre-commissioning of the wind turbine will occur next month. The towing to the SEM-REV test site off Le Croisic will occur later this autumn where the floating system will be connected to the grid and hooked-up to the mooring lines which were successfully pre-installed last month. These site-specific construction and launching methods are one of several proposed by Ideol’s innovative technology as it has always been Ideol’s strategy to be fully flexible and adaptable to high local content possibilities and local site and/or infrastructure constraints. The installation of both tower and wind turbine on the floating structure at quay side is one of the many benefits a few floating offshore wind technologies such as Ideol’s can offer. This eliminates very costly and often hazardous offshore operations.

Installers are aware about this situation: the PV plant has been installed with an integrated PV monitoring system. And now the question arises, who will look after the reports and error notifications in the future. Binsdorf/Geislingen, Germany, August 22, 2017 - In some cases, the customers take care of monitoring their PV plants themselves - and according to the monitoring feedback, this might end up in a lot of workload. In such cases, problems can easily slip by undetected, leading to high yield losses. Another option is that the installers enter into a service contract with their customers to monitor and service the PV plants. Such service contracts normally benefit both parties. The customer can sit back and relax since a PV professional is taking care of everything and is always available, if a problem occurs. Monitoring and service agreements offer installers the option to establish and expand their customer base as well. Every service, of course, involves a certain amount of time that is agreed upon by the installers. In practice, this means analyzing incoming error notifications and the possible causes, e.g. detecting a string failure and fixing the problem. When monitoring a small number of plants, this is not a major
