Twisting underneath the stroboscope — Controlling crystal lattices of hybrid photo voltaic cell supplies with terahertz mild

To beat world power challenges and battle the looming environmental disaster, researchers all over the world examine new supplies for changing daylight into electrical energy. A few of the most promising candidates for high-efficiency low-cost photo voltaic cell purposes are primarily based on lead halide perovskite (LHP) semiconductors. Regardless of record-breaking photo voltaic cell prototypes, the microscopic origin of the surprisingly wonderful optoelectronic efficiency of this materials class continues to be not fully understood. Now, a global staff of physicists and chemists has demonstrated laser-driven management of elementary motions of the LHP atomic lattice.
