Absorption enhancement in InGaN-based photonic crystal-implemented solar cells
(SPIE, 2012-07-26)We investigate the absorption characteristics of InGaN solar cells with high indium (0.8) content and a one-dimensional periodic nano-scale pattern (implemented) in the InGaN layer theoretically. The short-circuit current ... -
Absorption enhancement of molecules in the weak plasmon-exciton coupling regime
(Optical Society of American (OSA), 2014)We report on the experimental and theoretical investigations of enhancing the optical absorption of organic molecules in the weak plasmon-exciton coupling regime. A metal-organic hybrid structure consisting of dye molecules ... -
An analysis for the broad-band absorption enhancement using plasmonic structures on uncooled infrared detector pixels
(SPIE, 2012-05)This paper introduces an analysis on the absorption enhancement in uncooled infrared pixels using resonant plasmon modes in metal structures, and it reports, for the first time in literature, broad-band absorption enhancement ... -
Broadband absorption enhancement in an uncooled microbolometer infrared detector
(SPIE, 2014)This paper introduces a method for a broadband absorption enhancement in the LWIR range (8-12 μm), in single layer microbolometer pixels with 35 μm pitch. For the first time in the literature, this study introduces a very ... -
Plasmonic nanoslit array enhanced metal-semiconductor-metal optical detectors
(Institute of Electrical and Electronics Engineers, 2012-01-09)Metallic nanoslit arrays integrated on germanium metal-semiconductor-metal photodetectors show many folds of absorption enhancement for transverse-magnetic polarization in the telecommunication C-band. Such high enhancement ... -
Triangular metallic gratings for large absorption enhancement in thin film Si solar cells
(Optical Society of American (OSA), 2012)We estimate high optical absorption in silicon thin film photovoltaic devices using triangular corrugations on the back metallic contact. We computationally show 21.9% overall absorptivity in a 100-nmthick silicon layer, ...
