Matthew Gunther for Chemistry World: Perovskite solar cells may one day rival silicon-based technologies, but their performance outside the laboratory has been a constant source of contention in the past year. Now, an international team of scientists has manufactured the first thin film perovskite solar cell with a reported efficiency that has beenofficially recognised by an accredited national test laboratory.1 Since their development in 2012, the performance of light-harvesting metal–organo halide structures has seemingly improved at a staggering rate, with their efficiency increasing by six percentage points in just two years – the same increase took multi-crystalline solar cells over two decades. But their stability has been brought into question, with some international test centres taking issue with perovskite solar cells that are so unstable that they may degrade spontaneously in air, making it hard for them to assess their performance. It’s a state of affairs that Michael Grätzel from the Ecole Polytechnique Fédérale de Lausanne in Switzerland has had trouble dealing with. ‘Conspicuously, you could see that from the very beginning there was very scarce information on the stability of these devices,’ comments Grätzel. ‘I have raised that issue many times – one would think that now everybody does stability work after this alarm was sounded, but not so.'

KINGSPAN ENERGY COMPLETES SUNPOWER SOLAR INSTALLATION AND ENERGY EFFICIENCY UPGRADES FOR CARL ZEISS COMPANY
Unique integrated project reduces energy load of the Company's Training Center by 60 percent
With HD-Wave technology, SolarEdge initially creates a much smoother sine wave (a high-definition wave) thus avoiding the heavy and costly magnetic components while gaining efficiency.
Cole Mellino for EcoWatch: Morocco imports 97 percent of its energy, and yet it has one of the highest rates of solarinsolation of any country—about 3,000 hours of sunshine per year, according to the Solar GCC Alliance. To put that in perspective, the Guinness Book of World Records puts Yuma, Arizona as the sunniest place on Earth with an average of 4,055 hours of sunshine per year (the theoretical maximum is 4,456), whereas the sunniest place in Germany, which still has a robust solar industry, gets a mere 1,800 sunshine hours a year. So it’s no surprise that Morocco is tapping into its abundant sunshine for energy. Morocco is building “a complex of four linked solar mega-plants that, alongside hydro andwind, will help provide nearly half of Morocco’s electricity from renewables by 2020,” reports The Guardian. When the entire project is finished, it will be the world’s largest concentrated solar power plant in the world. The first phase, Noor 1, will go live next month. Cont'd...

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
