Disorder Engineered Inorganic Nanocrystal Solar Cells
March 30, 2022 | Leave a Comment
Researchers at The Institute of Photonic Sciences report on a novel disorder-engineering technique for inorganic solar cells that achieves a record-breaking power conversion efficiency. Now displayed over roof tops and in solar farms, silicon-based solar cells are, so far, one of the most efficient systems in generating electricity from sunlight, but their fabrication can be […]

New Inexpensive Passive Solar Powered Water Desalination
March 17, 2022 | Leave a Comment
Massachusetts Institute of Technology researchers have developed a desalination system that is more efficient and less expensive than previous methods. In addition to providing fresh water, the process could be used to treat contaminated wastewater or generate steam for sterilizing medical instruments, all without requiring a power source other than sunlight. An estimated two-thirds of […]

University of Cambridge researchers have made tiny ‘skyscrapers’ for communities of bacteria, helping them to generate electricity from just sunlight and water. The researchers used 3D printing to create grids of high-rise ‘nano-housing’ where sun-loving bacteria can grow quickly. Then they were able to extract the bacteria’s waste electrons, left over from photosynthesis, which could […]

University of Southern California researchers are asking what if surplus renewable energy could be stored as computation instead? Renewable energy has an intermittency problem – the sun provides no power at night, while winds can stop suddenly. Better battery storage is considered key to solving the intermittency problem by storing energy when the wind and […]
