Silicon dominates the world of solar power. Even the newest solar cell designs, tandem devices that have a silicon solar cell below a cell made of a crystalline material called a perovskite, rely on the material. Now, researchers are doing away with silicon altogether, creating tandems from two layers of perovskites, each tailored to absorb a different part of the solar spectrum. Because perovskites are easier to manufacture than silicon cells, the advance could lead to less costly solar power. According to sciencemag, Silicon solar cells have already made a considerable impact on energy markets. Improvements in technology and manufacturing have dropped the price of these cells some 88% in the past decade, according to a recent analysis by Lazard, a global financial analysis firm. Perovskite solar cells aim to build on these trends. These crystalline materials, typically made from lead, iodine, bromine, and other abundant elements, are cheap to make; unlike silicon, they are easy to process into sunlight-absorbing layers. Their efficiency at converting sunlight into electricity has also risen to near the level of the best silicon solar cells: from just 3.8% to more than 24% over the past decade. --------------------***-------------------- Source:https://tinyurl.com/y5meed85 Photo:www.sciencemag.org ……………………………………. ‘All rights to go to the author of the news & image as mentioned above’ -------------------------------------------
