The photoelectric effect provides the basis for solar energy and global communications; Albert Einstein described it over a century ago. For the first time, scientists from the Technical University of Munich (TUM), the Max-Planck Institute of Quantum Optics (MPQ), and the TU Wien have now measured the absolute duration of the light absorption and of the resulting photoelectron released from a solid body.
