Gold Nanorods for application in Plasmonic Luminescent Solar Concentrators
Mc Cormack, Sarah; Sethi, Arunima; Ahmed, Hind; Chandra, Subhash (2017)Luminescent solar concentrator (LSC) device is based on energy down shifting phenomenon with a primary goal of trapping, and concentrating solar radiation. The trapped light is guided to the photovoltaic cell through total ... -
Improving the Mathematical Model for Luminescent Down-Shifting Layers by Investigating their Loss Mechanisms
RAFIEE, MEHRAN; Ahmed, Hind; Chandra, Subhash; McCormack, Sarah J. (2017)A Luminescent Down-Shifting (LDS) layer is an optical approach to improve the solar cell’s optical response by using luminescent species doped in a polymer matrix material to form a thin layer to be deposited on top of the ... -
Optimization and Photostability Studies of Luminescent Organic Dyes for Solar Devices
GILLIGAN, SARAH; McCormack, Sarah J.; Ahmed, Hind; Chandra, Subhash (2018)The overall efficiency of a solar cell is limited due to high energy photons within the UV region not being used efficiently. Luminescent Down-Shifting (LDS) layers are used to convert the high energy photons to a lower ... -
Quantum Dot Luminescent Solar Concentrator: Optimization of Concentration and Thickness
RAFIEE, MEHRAN; Chandra, Subhash; Ahmed, Hind; McCormack, Sarah J. (2017)The absorption coefficient of a Luminescent Solar Concentrator (LSC) can non-linearly affect the total optical efficiency (η_opt) and solar concentration ratio (C_P) of the device. Absorption is determined by two critical ...
