Realizing omnidirectional light harvesting by employing

To improve the omnidirectional light-harvesting in dye-sensitized solar cells (DSSCs), here we present a dandelion-like structure composed of ZnO hemispherical shells and nanorods. Uniformly distributed hemispherical shells effectively suppress the reflection over the broadband region at incident angles up to 60°, greatly improving the optical absorption of the DSSCs. In addition, modulating

Modeling Light Trapping in Nanostructured Solar Cells

The integration of nanophotonic and plasmonic structures with solar cells offers the ability to control and confine light in nanoscale dimensions. These nanostructures can be used to couple incident sunlight into both localized and guided modes, enhancing absorption while reducing the quantity of material. Here we use electromagnetic modeling to study the resonances in a solar cell containing

Photonic crystal light trapping: Beyond 30% conversion

6/2/2020· Ray-optics based light-trapping in a conventional cell provides negligible solar energy absorption beyond 1100 nm wavelength. Consequently, BGN reduces the efficiency of a conventional cell. In contrast, the PhC based cells exhibit multiple resonances due to PIR and vortex-like energy flow in the 1100–1200 nm wavelength range.

OSA | Light trapping in solar cells: simple design rules

Solar cells can strongly benefit from optical strategies capable of providing the desired broadband absorption of sunlight and consequent high conversion efficiency. While many diffractive light-trapping structures prove high absorption enhancements, their industrial application rather depends on simplicity concerning the integration to the solar cell concept and the process technology.

Theoretical Study of Light Trapping in Nanostructured Thin

We propose and theoretically evaluate a plasmonic light trapping solution for thin film photovoltaic devices that comprises a monolayer or a submonolayer of wavelength-scale silver particles. We systematically study the effect of silver particle size using full-wave electromagnetic simulations. We find that light trapping is significantly enhanced when wavelength-scale silver particles rather
