A single cycle of intense Terahertz laser light (red) rapidly twists the atomic lattice of a hybrid organic-inorganic solar cell material. The resulting ultrafast shaking of the lead halide lattice is traced by stroboscopic snapshots using visible laser pulses (green). The observed lattice response provides novel insights into microscopic mechanisms for protecting electric charges and paves the way for ultrafast control of the material’s optoelectronic properties.
