Improved InxGa1_xP/GaAs /Ge tandem solar cell using light trapping engineering and multi-objective optimization approach

, 2020
In this paper, an analytical model for studying the effect of light trapping mechanism on tandem solar cell performance is developed. The proposed model considers diffraction grating morphology and antireflection coating of the InxGa1_xP/GaAs/Ge tandem ...

‘Trapped rainbow’ storage of light in metamaterials

Nature, 2007
Light usually propagates inside transparent materials in well known ways. However, recent research has examined the possibility of modifying the way the light travels by taking a normal transparent dielectric and inserting tiny metallic inclusions of various shapes and arrangements.

Absorption of Light by Trapped Electrons

Physical Review, 1953
A new method of approach to the problem of absorption of light by trapped electrons in crystals is presented. The method is based upon the use of the Slater sum for an oscillator (density matrix). The absorption cross section is calculated under the assumption of an electron-lattice coupling which is linear in the normal coordinates of the lattice ...

Plasmon enhanced light trapping in thin film GaAs solar cells by Al nanoparticle array

Physics Letters, 2019
Light trapping is a crucial factor to enhance the performance of thin film solar cells. For effective light trapping, we introduced Al nanoparticle array on the top and rear surface of thin film GaAs solar cells.

Bianisotropy for light trapping in all-dielectric metasurfaces

, 2020
Magnetoelectric dipole coupling effects in all-dielectric metasurfaces composed of particles with bianisotropic electromagnetic response are investigated. This bianisotropic response is associated with the trapped mode excitation. Maintaining the trapped

Superiority of random inverted nanopyramid as efficient light trapping structure in ultrathin flexible c-Si solar cell

Renewable Energy, 2019
In this work, random inverted nanopyramids (INPs) are fabricated as light trapping structures on ultrathin c-Si through a simple and cost-effective wet chemical method, followed by a systematic investigation of the photo-capturing properties of INPs ...

Light Trapping in Isotextured Silicon Wafers

IEEE Journal of Photovoltaics, 2017
We present an experimental investigation into light trapping within isotextured wafers. Measurements of reflectance and transmittance are performed on Si wafers both before and after the deposition of thin films on their surfaces.

Accurate Calculation of the Absorptance Enhances Efficiency Limit of Crystalline Silicon Solar Cells With Lambertian Light Trapping

IEEE Journal of Photovoltaics, 2018
The widely accepted limiting efficiency for crystalline silicon solar cells with Lambertian light trapping under 1 sun was previously calculated to be 29.43% for a 110-μm-thick device by using the commonly applied weak absorption approximation for light ...
