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 ... -
Analysis of the mosaic defects in graded and non graded InxGa1‐xN solar cell structures
(Süleyman Demirel Üniversitesi, 2017)In this study, graded (A) InxGa1‐xN (10.5 ≤ x ≤ 18.4) and non graded (B) InxGa1‐xN (13.6 ≤ x ≤ 24.9) samples are grown on c‐oriented sapphire substrate using the Metal Organic Chemical Vapour Deposition (MOCVD) technique. ... -
A baseball-bat-like CdTe/TiO2 nanorods-based heterojunction core–shell solar cell
(Elsevier, 2013)Rutile TiO2 nanorods on fluorine-doped thin oxide glass substrates via the hydrothermal technique were synthesized and decorated with a sputtered CdTe layer to fabricate a core-shell type n-TiO2/p-CdTe solar cell. Absorbance ... -
Enhancement of polycrystalline silicon solar cells efficiency using indium nitride particles
(Institute of Physics Publishing Ltd., 2015)In this work, we present a hybrid indium nitride particle/polycrystalline silicon solar cell based on 230 nm size indium nitride particles (InN-Ps) obtained through laser ablation. The solar cell performance measurements ... -
Investigation of lithium salts-nonionic surfactant lyotropic liquid crystalline mesophases in a dye sensitized solar cell as gel electrolyte
(Bilkent University, 2015-09)Liquid crystals are one of the most widely studied and used materials in chemistry. The properties of liquid crystals make them interesting to research also for various electrochemical applications. In this context, lithium ... -
Investigation on lithium salt - surfactant lyotropic liquid crystalline mesophases: characterization, role of water, and electrochemical behaviors
(Bilkent University, 2021-09)In this thesis, lyotropic liquid crystalline (LLC) mesophases of lithium salts (LiCl, LiBr, LiNO3, LiSCN, LiI, LiI/I2, and LiH2PO4) and 10-lauryl ether (C12H25(OCH2CH2)10OH, C12EO10) have been investigated and the LiI/I2 ... -
Nanosecond pulsed laser ablated sub-10 nm silicon nanoparticles for improving photovoltaic conversion efficiency of commercial solar cells
(Institute of Physics Publishing Ltd., 2017)In this paper, we demonstrate the enhancement of photovoltaic (PV) solar cell efficiency using luminescent silicon nanoparticles (Si-NPs). Sub-10 nm Si-NPs are synthesized via pulsed laser ablation technique. These ultra-small ... -
Scattering analysis of silver nanoparticles for solar cell applications using integral equations
(IEEE, 2018)Plasmonic nanoparticles (NPs) can be used to improve the efficiency of solar cells. Analysis of electromagnetic scattering from NPs is often carried out under the assumptions that they reside in air and have 'ideal' shapes ... -
Thickness dependence of solar cell efficiency in transition metal dichalcogenides MX2 (M: Mo, W; X: S, Se, Te)
(Elsevier, 2020)Bulk transition metal dichalcogenides are indirect gap semiconductors with optical gaps in the range of 0.7–1.6 eV, which makes them suitable for solar cell applications. In this work, we study the electronic structure, ...
