Hybrid Vapor-Solution Sequentially Deposited Mixed-Halide Perovskite Solar Cells
Soltanpoor, Wiria; Dreessen, Chris; Şahiner, Mehmet Cem; Susic, Isidora; Afshord, Amir Zarean; Chirvony, Vladimir S.; Boix, Pablo P.; Günbaş, Emrullah Görkem; Yerci, Selçuk; Bolink, Henlk J. (2020-08-01)
The recent sky-rocketing performance of perovskite solar cells has triggered a strong interest in further upgrading the fabrication techniques to meet the scalability requirements of the photovoltaic industry. The integrat...
Preparation and Characterization of Mixed Halide MAPbI(3-x)Cl(x) Perovskite Thin Films by Three-Source Vacuum Deposition
Babaei, Azin; Soltanpoor, Wiria; Tesa-Serrate, Maria A.; Yerci, Selçuk; Sessolo, Michele; Bolink, Henk J. (2020-04-01)
Chloride is extensively used in the preparation of metal halide perovskites such as methylammonium lead iodide (MAPbI(3-x)Cl(x)), but its persistence and role in solution-processed materials has not yet been rationalized. ...
Combined Optical-Electrical Optimization of Cd1-xZnxTe/Silicon Tandem Solar Cells
Koc, Mehmet; Kartopu, Giray; Yerci, Selçuk (2020-04-01)
Although the fundamental limits have been established for the single junction solar cells, tandem configurations are one of the promising approaches to surpass these limits. One of the candidates for the top cell absorber ...
Engineering spin and antiferromagnetic resonances to realize an efficient direction-multiplexed visible meta-hologram
Ansari, Muhammad Afnan; Kim, Inki; Rukhlenko, Ivan D.; Zubair, Muhammad; Yerci, Selçuk; Tauqeer, Tauseef; Mehmood, Muhammad Qasim; Rho, Junsuk (2020-01-01)

Guideline for Optical Optimization of Planar Perovskite Solar Cells
Koc, Mehmet; Soltanpoor, Wiria; Bektas, Gence; Bolink, Henk J.; Yerci, Selçuk (2019-12-01)
Organometallic halide perovskite solar cells have emerged as a versatile photovoltaic technology with soaring efficiencies. Planar configuration, in particular, has been a structure of choice thanks to its lower temperatur...
A Single-Layer Dielectric Metasurface Enabling Wave Incidence Direction Control
Ansari, Muhammad Afnan; Mehmood, Muhammad Qasim; Kim, Inki; Waseem, Muhammad Hamza; Tauqeer, Tauseef; Yerci, Selçuk; Rho, Junsuk (2019-09-20)
Multi-layer three-dimensional (3D) metamaterials have emerged as a platform to realize multifunctional chiral devices such as for asymmetric transmission. However, the alignment and fabrication methods of 3D chiral metamat...
Analysis of Field-Effect Passivation in Textured and Undiffused Silicon Surfaces
Turkay, Deniz; Koroglu, Cagil; Yerci, Selçuk (2019-09-13)
In this work, we present a numerical analysis comparing the field-effect passivation provided by fixed dielectric charges on planar and textured undiffused silicon surfaces. We focus particularly on the ratio of effective ...
Study of thin film poly-crystalline CdTe solar cells presenting high acceptor concentrations achieved by in-situ arsenic doping
Kartopu, G.; Oklobia, O.; Turkay, D.; Diercks, D. R.; Gorman, B. P.; Barrioz, V.; Campbell, S.; Major, J. D.; Al Turkestani, M. K.; Yerci, Selçuk; Barnes, T. M.; Beattie, N. S.; Zoppi, G.; Jones, S.; Irvine, S. J. C. (2019-06-01)
Doping of CdTe using Group-V elements (As, P, and Sb) has gained interest in pursuit of increasing the cell voltage of CdTe thin film solar devices. Studies on bulk CdTe crystals have shown that much higher acceptor concen...
