Researchers from ETH Zurich, Empa and Stanford have taken snapshots of the crystal structure of perovskite nanocrystals as it was deformed by excited electrons. To their surprise, the deformation ...

Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are ...

A molecular process called singlet fission might boost solar-cell efficiency, but the mechanism must first be determined. A technique that probes molecules undergoing this process finally reveals the ...

Measurements and modeling of femtosecond-pumped indium tin oxide identified the electronic limit of optical switching and ...

A new study, published in early November in Nature Physics, details a breakthrough in understanding the dynamics of halide perovskites, revealing insights crucial for advancing optoelectronics ...

A better understanding of how electrons convert energy into photons could lead to designing more efficient solar cells or better phototherapies for cancer. Researchers looking into the process have ...

Researchers precisely time the motions of individual, energetic electrons moving in a solid. Over the top. Individual electrons (blue) emitted from a distant source will surmount a time-varying ...
