Reducing light reflection of CIGS solar cells with SiO₂ sandwiched by a metal nanoparticle structure

Exploiting the Optical Limits of Thin‐Film Solar Cells: A Review on Light Management Strategies in Cu(In,Ga)Se2

“…Resonant architectures have the potential to promote a more efficient light incoupling and increased optical path length at specific wavelength values, when compared with the microscale approach. Here, configurations such as periodic gratings, [128][129][130] plasmonic NPs, [70,[131][132][133][134][135][136][137][138] and dielectric nanostructures [70,[139][140][141] are included. Morphology-dependent light scattering and/or localization can be achieved through schemes exploiting resonant photonic or plasmonic effects.…”

“…Wavelength-selective resonant architectures on the solar cell interfaces have been commonly integrated through metallic or dielectric NPs. [41,70,[131][132][133][134][135][136][137][138]141] Plasmonic architectures present additional benefits, as compared with the typical periodic mesoscale gratings. The resonant optical behavior of metallic NPs is a result of the free-electron motion.…”
