Scientists at Germany’s Fraunhofer Institute for Solar Energy Systems have broken two of their own records for cell efficiency, working with silicon and III-V material tandem cells. The institute hit 34.1% on a triple junction cell using wafer bonding technology and 24.3% by directly depositing III-V layers onto a silicon solar cell.

With the benefits solar panels can bring to cropland being considered in Europe, PV and aquaculture are working in tandem in Vietnam. Shrimp and fish farming requires land and lots of water but solar panels are helping mitigate those demands.

Scientists at the Royal Melbourne Institute of Technology have developed a method for producing a ‘smart fabric’ with a supercapacitor energy storage device embedded in it. Its developers say it can be readily integrated with a solar cell or used to power wearable technology.

While based in Munich in Germany’s south, renewable asset management software provider 3megawatt’s first major clients were in the United States. However, as the European markets have transitioned beyond feed-in tariffs to the complexity of subsidy-free solar and wind arrays, the understanding of the need for asset management tools is rapidly increasing, says 3megawatt founder and CEO Edmee Kelsey.

X-ray analysis is said to have solved the mystery of how to preserve optical absorption in perovskite layers. Researchers say the discovery could help stabilize the material and speed up the launch of a new ingredient for PV research.

Two reports have described how the world’s largest renewable energy market is moving towards maturity. According to the Brookings Institution, the Chinese clean energy market could become more open to Western investors and tech. A report by Fitch claims projects are moving back to inland provinces from coastal regions.

Engie has raised eyebrows with the installation of several solar benches in Biarritz, southwestern France, as a local official has asked citizens to avoid sitting on them for long periods of time in order to keep their energy yield up. But the authorities over in Cannes are clearly impressed, as the municipal government in the French Riviera resort town has also revealed plans to buy more of the PV benches, which are designed by Croatian startup Include.

The improved performance was achieved by using a methylene bridged material, the molecular dye DfZnP-iPr.

Traditional solar cookers concentrate sunlight on mirrored surfaces and convert it into heat. But this summer, Sunspot unveiled Sunspot Solar Electric Cooking, a new cooker based on PV technology. The system relies on two PV modules, a lead-carbon battery, an inverter, and an induction cooktop.

MIT researchers say climate change could reduce the yield of solar modules. Analysis based on the warming scenarios outlined by the IPCC predicts in some areas the annual energy output of PV systems may fall by up to 50 kWh per kilowatt installed.
