Ultrathin UV Light Absorber Developed

Ultraviolet light (UV) has not only harmful effects on molecules and biological tissue like human skin but it also can impair the performance of organic solar cells upon long-term exposure. Researchers of Kiel University and Helmholtz-Zentrum Geesthacht have now developed a so-called plasmonic metamaterial, which is compatible with solar technology and completely absorbs UV light—despite being only 20 nanometers thin. Continue reading Ultrathin UV Light Absorber Developed

Research teams at the Helmholtz-Zentrum Berlin for Materials and Energy (HZB) and at the University of Limerick, Ireland, have discovered a novel solid state reaction that can create a kesterite thin film solar cell absorber from a carpet of nanorods within a few seconds. Continue reading Novel Reaction Creates Solar Cell Material in Seconds

Scientists Uncover Charge Transfer Mechanism in Perovskite Solar Cells

Lead halide perovskites have recently been used as light absorbers in hybrid organic–inorganic solid-state solar cells, with efficiencies as high as 15% and open-circuit voltages of 1 V. However, a detailed explanation of the mechanisms of operation within this photovoltaic system is still lacking. Scientists from Ecole polytechnique fédérale in Lausanne (EPFL) and of HZB-Institute for Solar Fuels have now uncovered the mechanism by which these novel light-absorbing semiconductors transfer electrons along their surface.
