Using the tools of physics and design principles, AMOLF researchers study complex matter, such as light at the nanoscale, living matter, designer matter and nanoscale solar cells. These insights open up opportunities to create new functional materials and to find solutions to societal challenges.
Solar cell material performs better under pressure
A novel and highly promising material for solar cells, halide perovskites, is more stable and consequently more efficient if just one ion is substituted. Researchers from AMOLF revealed in an unexpected manner why this is the case: pressure plays an important role. They published their findings on July 15th in Cell Reports Physical Science.
Olive oil sheds new light on universality in phase transitions
A simple drop of olive oil in a system of photons bouncing between two mirrors, has revealed universal aspects of phase transitions in physics. Researchers at AMOLF used an oil-filled optical cavity in which light undergoes phase transitions similar to those in boiling water. The system they studied has memory because the oil causes photons to interact with themselves. By varying the distance between the two mirrors and measuring the transmission of light through the cavity, they discovered a universal law describing phase transitions in systems with memory.
