Leipzig physicists show that light can generate electricity even in translucent materials
News from Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists from Leipzig University and Nanyang Technological University in Singapore have managed to prove this. "This opens new paradigms for constructing opto-electronic and photovoltaic devices, such as light amplifiers, sensors and solar cells," says Inti Sodemann Villadiego, Professor at the Institute of Theoretical Physics at Leipzig University.

Mysterious object in the gap
Mysterious object in the gap
On May 29, 2023, the LIGO Livingston detector observed a mysterious signal, called GW230529. It originated from the merger of a neutron star with an unknown compact object, most likely an unusually light-weight black hole. With a mass of only a few times that of our Sun, the object falls into the "lower mass gap" between the heaviest neutron stars and the lightest black holes.
