Perovskite solar technology shows quick energy returnsJuly 17, 2015

Silicon-based solar panels, which dominate the market for solar power, usually need about two years to “pay back” the energy used to make them. But for technology made with perovskites—a class of materials causing quite a buzz in the solar research community—the energy payback time is only two to three months.

Dynamic Non-equilibrium, Rate, Time and History Dependent Molecular Interactions in Colloidal and Biocolloidal Systems


With the increasing appreciation of the complexity of colloidal and biological systems – now also referred to complex fluid and soft material systems – many more types of rate, time, and history-dependent processes, including the interaction potentials themselves, have appeared whose main feature is their non-equilibrium nature.

Studies of Nanoscale Dynamics and Strain Development in Materials: Applications and Perspective on Coherent X-rays
Coherent x-rays available from the third generation synchrotron sources have opened many new avenues of research, e.g., measuring dynamics by X-ray photon correlation spectroscopy (XPCS) and giving major impact on imaging techniques such as coherent x-ray diffraction (CXD). The recent advent of hard x-ray free electron lasers (XFELs) opens new areas of science due to their exceptional brightness, coherence, and time structure. In principle, such sources enable studies of dynamics of condensed matter systems over times ranging from femtoseconds to seconds.
