Polaritons combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors. However, they are difficult to control, and much of their behavior is a mystery. Now, scientists have found a way to tune the speed of this energy flow.
Researchers have developed a tandem solar cell that can deliver a certified efficiency of 29.2%. This achievement was made possible by combining a perovskite solar cell with a textured silicon solar cell.
Using redox-active electrolytes to boost graphene electrodes is a highly-efficient strategy to increase the capacitive performance of micro-supercapacitors.
Researchers found that ribbon-like thin films, grown through a bottom-up, self-assembly approach, can act as ultrahigh-quality nanoscale resonators of lattice vibrations at infrared frequencies.
