Scientists from France’s CEA-Ines developed a 400 W micro-inverter with a power density of 1.1 kW/L and an efficiency of 97%. The device utilizes GaN 600V diodes and power transistors developed by CEA’s electronic branch CEA-Leti.

French researchers have developed PV modules with an area of 11.6 square centimeters for indoor applications. They said the achieved efficiency level marks a world record for a flexible perovskite device larger than 10 square centimeters.

French solar energy institute INES has developed new PV modules with thermoplastics and natural fibers sourced in Europe, such as flax and basalt. The scientists aim to reduce the environmental footprint and weight of solar panels, while improving recycling.

The Sun Horizon consortium has started to collect performance data on two pilot projects that combine heat pumps with solar systems using hybrid panels on homes in Riga, Latvia. The solution features a heat pump for space heating and domestic hot water and PVT panels to produce power for heating and domestic appliances, with excess power fed to the grid.

Scientists in France conducted an analysis on the competitiveness of water desalination, taking a large scale project planned for Morocco as a case study. The research concludes that PV without storage is the cheapest option to power desalinators, and will likely remain so until at least 2030.

The Smart Energy Hub can operate in electrolysis mode to store renewable energy as hydrogen, or in fuel cell mode to produce electricity and heat from previously produced hydrogen or methane. Its developers are the French Alternative Energies and Atomic Energy Commission and start-up Sylfen.
