We present new types of nanocavities to improve the absorption of solar cells for energy harvesting in wide frequency ranges of the optical spectrum. Using a full‐wave approach, as opposed to the commonly used ray‐based modeling of the light, antenna‐inspired cavities with horn shapes are proposed and introduced. The effectiveness of the designed cavities is demonstrated in comparison to the conventional textures involving inverted pyramids and nanocones. Highly accurate numerical results show that solar‐cell structures with horn‐type cavities can provide excellent absorbance rates, even without using any matching layer.

Enhanced second harmonic generation from coupled asymmetric plasmonic metal nanostructures Yıldız, Bilge Can; Taşgın, Mehmet Emre; Abak, Musa Kurtuluş; Coskun, Sahin; Ünalan, Hüsnü Emrah; Bek, Alpan (IOP Publishing, 2015-12-01) We experimentally demonstrate that two coupled metal nanostructures (MNSs), a silver nanowire and bipyramid, can produce similar to 30 times enhanced second harmonic generation compared to the particles alone. We develop a simple theoretical model, presenting the path interference effects in the nonlinear response of coupled MNSs. We show that the reason for such an enhancement can be the occurrence of a Fano resonance due to the coupling of the converter MNS to the long-lived mode of the attached MNS.
High Conversion Efficiency InP/InGaAs Strained Quantum Well Infrared Photodetector Focal Plane Array With 9.7 mu m Cut-Off for High-Speed Thermal Imaging Eker, Suleyman Umut; Arslan, Yetkin; Onuk, Ahmet Emre; Beşikci, Cengiz (Institute of Electrical and Electronics Engineers (IEEE), 2010-02-01) InP/InGaAs material system is an alternative to AlGaAs/GaAs for long wavelength quantum well infrared photodetectors (QWIPs). We demonstrate a large format (640 x 512) QWIP focal plane array (FPA) constructed with the strained InP/InGaAs material system. The strain introduced to the structure through utilization of In0.48Ga0.52As (instead of In0.53Ga0.47As) as the quantum well material shifts the cut-off wavelength from similar to 8.5 to 9.7 mu m. The FPA fabricated with the 40-well epilayer structure yield...
QWIP focal plane arrays on InP substrates for single and dual band thermal imagers Eker, S. U.; Arslan, Y.; Kaldirim, M.; Beşikci, Cengiz (Elsevier BV, 2009-11-01) Alternative material systems on InP substrate provide certain advantages for mid-wavelength infrared (MWIR), long-wavelength infrared (LWIR) and dual band MWIR/LWIR quantum well infrared photodetector (QWIP) focal plane arrays (FPAs). While InP/InGaAs and InP/InGaAsP LWIR QWIPs provide much higher responsivity, when compared to the AlGaAs/CaAs QWIPs, AllnAs/InGaAs system facilitates completely lattice matched single band MWIR and dual band MWIR/LWIR FPAs.
First-principles design of efficient solar cells using two-dimensional arrays of core-shell and layered SiGe nanowires Pekoz, R.; Malcıoğlu, Osman Barış; Raty, J. -Y. (American Physical Society (APS), 2011-01-20) Research for third generation solar cell technology has been driven by the need to overcome the efficiency and cost problems encountered by current crystalline Si- and thin-film-based solar cells. Using first-principles methods, Ge/Si and Si/Ge core/shell and Si-Ge layered nanowires are shown to possess the required qualities for an efficient use in photovoltaic applications. We investigate the details of their band structure, effective mass, absorption property, and charge-carrier localization. The strong ...
Electrical response of electron selective atomic layer deposited TiO2-x heterocontacts on crystalline silicon substrates Ahiboz, Doguscan; Nasser, Hisham; Aygun, Ezgi; Bek, Alpan; Turan, Raşit (IOP Publishing, 2018-04-01) Integration of oxygen deficient sub-stoichiometric titanium dioxide (TiO2-x) thin films as the electron transporting-hole blocking layer in solar cell designs are expected to reduce fabrication costs by eliminating high temperature processes while maintaining high conversion efficiencies. In this paper, we conducted a study to reveal the electrical properties of TiO2-x thin films grown on crystalline silicon (c-Si) substrates by atomic layer deposition (ALD) technique. Effect of ALD substrate temperature, p...
