A new kind of near-invisible solar cell could one day help everyday glass surfaces generate electricity. This could include car windows and sunroofs, smart glasses, wearables, building façades, and home windows. Scientists at Nanyang Technological University, Singapore, have developed ultrathin transparent perovskite solar cells that are about 10,000 times thinner than a strand of human hair and around 50 times thinner than conventional perovskite solar cells. The NTU research team, led by Associate Professor Annalisa Bruno, published the findings in ACS Energy Letters (via TechXplore ). Can solar cells disappear into everyday glass? These solar cells are semi-transparent and color-neutral, so they could potentially be added to glass without making it look like traditional solar panels . This could be useful in cities where rooftops are already used for solar, but windows and vertical glass façades remain mostly untapped.…
