source:AZO materialsPerovskite Solar CellsPerovskite solar cells have advantages over current solar cell technology. They have the potential to be more efficient, are lightweight, and cost less than other variants. In a perovskite solar cell, the layer of perovskite is sandwiched between a transparent electrode at the front and a reflective electrode at the back of the cell.Electrode transport and hole transport layers are inserted between cathode and anode interfaces, which facilitates charge collection at the electrodes.There are four classifications of perovskite solar cells based on morpho...

source:nano werk(Nanowerk News) In an article published in the scientific journal Nature Communications ('Spatial coherence of room-temperature monolayer WSe2 exciton-polaritons in a trap'), an international team led by Oldenburg physicists Dr. Hangyon Shan, Prof. Dr Christian Schneider and Dr. Carlos Anton-Solanas reports that crystals consisting of just three atomic layers can emit laser-like light at room temperature. This new material thus has the potential to be used as a light source in miniaturized circuits and also in future quantum applications.Scientists have so far only been...

source:Eurasia ReviewLight bulbs are a big upgrade from fires and candles. Every year homes in informal settlements burn down in Africa because of fires used for heating and lighting.So electrical light bulbs with filaments brought about a revolution at home and work.Still, all these options are too hot to handle carelessly. They also give off lots of heat, and light up everything around them with a rosy-tinged hue.In other words, good for romance and atmosphere but not good for low lighting bills.Then fluorescent lighting came along, using much less energy. These are fragile, prone to flicker...
