Amorphous silicon, Materials science, genetic structures, business.industry, Photovoltaic system, Light absorbtion, Trapping, Coupled mode theory, Quantitative Biology::Cell Behavior, chemistry.chemical_compound, Optics, chemistry, Optoelectronics, Plasmonic solar cell, business, Absorption (electromagnetic radiation), Diffraction grating, Refractive index
Abstract

We explore the limit of absorption enhancement in thin film solar cells obtained by guided mode excitation and we discuss the geometrical and angular dependence of absorption. We consider the modal properties of the cell.

2. An RCWA Analysis of Solar Cell Back Reflectors: Comparison between Modelling and Experiment

Author

Christophe Ballif, Karin Söderström, Hans Peter Herzig, Ali Naqavi, Vincent Paeder, Franz-Josef Haug, and Toralf Scharf

Subjects
Diffraction, Materials science, business.industry, Surface plasmon, Finite-difference time-domain method, Physics::Optics, Polarization (waves), Diffraction efficiency, law.invention, Computational electromagnetic methods, Optics, Solar cell efficiency, law, Solar cell, Surface plasmon resonance, business, Photovoltaic, Gratings
Abstract

We present a comparison between spectrally-resolved reflection measurements of gratings and theoretical predictions from RCWA approach. Diffraction intensities vary significantly with polarization, and surface plasmon absorption is observed around the onset of the diffraction orders.
