Phys.org January 31, 2023 When light scatters off a sphere, it produces a rich Mie spectrum full of overlapping resonances. Single resonances can be explained with a quantum analogy and result in Fano profiles. However, the full spectrum is so complex that recognizable patterns have not been found, and is only understood by comparing to numerical simulations. An international team of researchers (Sweden, Mexico) has shown the directional Mie spectrum of evaporating water droplets arranged in consecutive Fano Combs. They explained it by expanding the quantum analogy. This turns the droplet into an “optical atom” with angular momentum, tunneling, and […]

Nanoparticles increase light scattering, boost solar cell performance
Phys.org August 3, 2022 An international team of researchers (USA – Pennsylvania State University, Australia, Italy) has demonstrated that adding any nanomaterial to solar material boosts its efficiency because of the enhanced light scattering as confirmed by theoretical calculations. Adding the nanoparticles boosted the efficiency of perovskite solar cells by 1% in the study. Redistribution of the optical field and consequently a homogenization of the optical field can lead to a reduced photocarrier loss and provide a noticeable photocurrent enhancement (ca. 7%), which explains the general photocurrent improvement in solar cells with nanomaterials…read more.
