Researchers boost performance quality of perovskites
Solar cells are devices that absorb photons from sunlight and convert their energy to move electrons—enabling the production of clean energy and providing a dependable route to help combat climate change. But most solar ...
The true power of the solar wind
The planets and moons of our solar system are continuously being bombarded by particles hurled away from the sun. On Earth this has hardly any effect, apart from the fascinating northern lights, because the dense atmosphere ...
Double-layered porous nanotubes with spatially separated photoredox surfaces
Solar energy conversion of water into H2 through photocatalysis is considered a promising approach for H2 production. However, the separation efficiency of charge carriers is the key to improving the efficiency of photocatalytic ...
Transparent, conductive films promising for developing flexible screens
Researchers have demonstrated large-scale fabrication of a new type of transparent conductive electrode film based on nanopatterned silver. Smartphone touch screens and flat panel televisions use transparent electrodes to ...
Connecting the sea to the sky in the high Arctic
How important is marine microbiology to clouds in the summertime high Arctic and how important is this connection for climate in the region? This is a key focus of a research expedition on the Swedish icebreaker Oden that ...
New views of Sun: Two missions will go closer to our star than ever before
As we develop more and more powerful tools to peer beyond our solar system, we learn more about the seemingly endless sea of faraway stars and their curious casts of orbiting planets. But there's only one star we can travel ...
Research gets closer to producing revolutionary battery to power renewable energy industry
Any resident of the Great Plains can attest to the massive scale of wind farms that increasingly dot the countryside. In the Midwest and elsewhere, wind energy accounts for an ever-bigger slice of U.S. energy production: ...
Special star is a Rosetta Stone for understanding the sun's variability and climate effect
The spots on the surface on the sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven by the solar dynamo, which is an interplay between magnetic fields, convection and rotation. ...
Glass microparticles enhance solar cells efficiency
Scientists from ITMO University have suggested a new solar cell coating that combines features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid ...
