The university’s new Initiative for Sustainable Energy will focus on renewable energy, energy efficiency, and sustainable fuels and materials.
A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking water supplies. The approach should be efficient and economic, even down to part-per-billion levels of contamination.
May 11, 2021 Share Perovskites are a category of materials with a distinct crystalline atomic structure. Just over ten years ago, scientists found that perovskites are exceptionally good at absorbing light. The discovery set off an overwhelming flow of new research into perovskite solar cells. Since then, the efficiency of those solar cells has increased substantially and now rivals that of conventional silicon cells. In manufacturing, perovskite cells are superior because they’re much more effortless and require less energy consumption. The light absorber can be made at near room ...

Scientists have developed a new, more stable type of perovskite solar cell that uses molecular glue to form strong bonds between its layers Padture Lab/Brown University 1/1 Scientists have developed a new, more stable type of perovskite solar cell that uses molecular glue to form strong bonds between its layers Padture Lab/Brown University In a relatively short space of time, perovskite solar cells have become a highly promising candidate when it comes to how we migh...
A “molecular glue” dramatically increases the stability and reliability of perovskite solar cells over time, researchers report in a new study. The treatment, which keeps a key interface inside the cells from degrading, also improves the efficiency with which they convert sunlight into electricity. “There have been great strides in increasing the power-conversion efficiency of perovskite solar cells,” says senior author Nitin Padture, a professor of engineering at Brown University. “But the final hurdle to be cleared before the technology can be widely available is reliability—mak...
