The breakthrough overcomes the long-standing limit of conventional solar cells to achieve an energy conversion efficiency of ...

Japanese researchers developed a molybdenum-based spin-flip emitter that efficiently harvests triplet excitons from ...

Two-dimensional (2D) materials have proved to be a promising platform for studying exotic quasiparticles, such as excitons. Excitons are bound states that emerge when an electron in a material absorbs ...

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 ...

The ability to move electron-hole pairs—called excitons—in desired directions is important for generating electricity and creating fuels. This happens naturally in photosynthesis, making it a source ...

Coulombic attraction between a negatively charged electron and a positively charged hole form excitons. The photoexcitation in semiconductors exhibits a spectrally narrow linewidth resulting in ...

Researchers have created an even more exotic form of the exciton-polariton, one which has a defined quantum spin that is locked to its direction of motion. Depending on the direction of their spin, ...

After nearly a century of probing the nature of tiny, ephemeral objects called excitons, researchers finally managed to image the structure, hinting at the true location of an electron. The findings ...
