Topological light-trapping on a dislocation [PDF]

Nature Communications, 2018
Although topological confinement of waves to the edges is common, lower-dimensional wave confinement is scarce. Here, Li et al. demonstrate that concurrent wavevector and real-space topology can lead to a topologically protected zero-dimensional cavity ...

Nanostructures for Light Trapping in Thin Film Solar Cells [PDF]

Micromachines, 2019
Thin film solar cells are one of the important candidates utilized to reduce the cost of photovoltaic production by minimizing the usage of active materials. However, low light absorption due to low absorption coefficient and/or insufficient active layer

Light Trapping in Single Elliptical Silicon Nanowires [PDF]

Nanomaterials, 2020
Light trapping in single nanowires (NWs) is of vital importance for photovoltaic applications. However, circular NWs (CNWs) can limit their light-trapping ability due to high geometrical symmetry.

Semiconductor-nanoantenna-assisted solar absorber for ultra-broadband light trapping [PDF]

Nanoscale Research Letters, 2020
Light trapping is an important performance of ultra-thin solar cells because it cannot only increase the optical absorption in the photoactive region but it also allows for the efficient absorption with very little materials.

Light Trapping with Silicon Light Funnel Arrays. [PDF]

Materials (Basel), 2018
Silicon light funnels are three-dimensional subwavelength structures in the shape of inverted cones with respect to the incoming illumination. Light funnel arrays can serve as an efficient absorbing layers on account of their light trapping capabilities associated with the presence of high density complex Mie modes.

Study about photoinduction-based technology for trapping small brown planthopper

Frontiers in Plant Science, 2022
To provide a theory to guide the selection of the illumination parameters of light emitting diode (LED)-based light sources used for trapping Laodelphax striatellus, we used LED light sources and devices built in-house to detect L.
