Perovskite solar cells have progressed in recent years with rapid increases in power conversion efficiency (from 3% in 2006 to 25.5% today), making them more competitive with silicon-based photovoltaic cells. However, a number of challenges remain before they can become a competitive commercial technology. Now a team at the NYU Tandon School […]
Inspired by nature, researchers at Pacific Northwest National Laboratory (PNNL), along with collaborators from Washington State University, created a novel material capable of capturing light energy. This material provides a highly efficient artificial light-harvesting system with potential applications in photovoltaics and bioimaging. The research provides a foundation for overcoming the difficult challenges […]
Three billion years ago, light first zipped through chlorophyll within tiny reaction centers, the first step plants and photosynthetic bacteria take to convert light into food. Heliobacteria, a type of bacteria that uses photosynthesis to generate energy, has reaction centers thought to be similar to those of the common ancestors for all photosynthetic organisms. […]
The photochemistry of the future will spring up human industry without smoke, and bring a brighter civilization based on the utilization of solar energy instead of fossil energy. Photochemistry has been used in controlling many reaction processes, especially for the challenging reactions containing selective C-H activation and C-C coupling in chemical synthesis. […]
Narrow-gap semiconductors with the ability to use visible light have garnered significant interest thanks to their versatility. Now, scientists in Japan have developed and characterized a new semiconductor material for application in process components stimulated by light. The findings have, for the first time, suggested a new way to reduce the band gap in […]
German chemicals giant BASF said Thursday it had agreed a partnership with Chinese firm Shanshan to produce components for batteries, including those used in electric cars, in China. In a statement, BASF said it had agreed to take on a 51 percent share of the joint venture to produce cathode active materials and precursors on […]
