Giant electric boiler energized by wind and solar in the Netherlands
Swedish energy company Vattenfall is planning to build a 150 MW electric boiler near Amsterdam under the Netherlands’ SDE+ program for large scale renewables. The facility is planned to operate when a lot of electricity from wind and sun is available and to supply hot water to households in the city and its surrounding areas.
Nano-micro-scale cooler for solar modules
The proposed technique is based on radiative cooling and consists of a glass coating made with a two-dimensional subwavelength nanostructured grating, which is imprinted in soda-lime glass and has enhanced mid-infrared emissivity, and a micro-structured grating. The temperature decrease provided by the nano-micro-grating coating was found to be approximately up to 5.8 degrees Celsius.

A touch of gold for a 19.8% efficient perovskite cell
Scientists in the U.S. fabricated a semitransparent perovskite solar cell that reached 19.8%, and 28.3% in a tandem cell stacked on top of a silicon-heterojunction device. The device relies on a film of gold just a few atoms thick, grown using an innovative seeding method, which has the valuable properties of being both highly conductive and transparent.
