Making the case for perovskite quantum dots
Quantum dots, a type of semiconductor based on tiny nanometer sized particles, are a cause for excitement in many disciplines thanks to their unique electronic properties. In solar cell technology, quantum dots fabricated from perovskites could have several advantages over more commonly researched “bulk” perovskite materials, and researchers are beginning to take note of these. A group of scientists in China evaluated recent progress in perovskite quantum dot solar cells, noting both strong potential and a long way to go for this early-stage technology.
Sub-nanometric particles to stabilize lithium-oxygen batteries
The storage technology promises ten times the energy density offered by lithium-ion batteries but notorious cycling instability remains a concern. Researchers in South Korea may have come a step nearer a solution.
