Book Part Citation - Scopus: 2Advanced Applications of Green Materials for Gas Separation and Storage(Elsevier, 2021) Kırbıyık Kurukavak, Çisem; Kuş, MahmutExtraordinary increase in global energy demand and supply, thus the environmental pollution, is one of the most important problem for today’s modern life. Gas separation and storage applications are closely related to control of the greenhouse gas and to use of clean and renewable energy. The development of green materials with desired combination properties and corresponding methods for target applications, which can minimize the environmental impact by using renewable sources has been having a growing attention over the last decades. Green and eco-friendly techniques, also called as “green chemistry, " focus on the processes and products, which reduce the use of hazardous substances and nonrenewable sources. Membrane separation, absorption, and physical adsorption for gas separation, purification, and storage are considered to be energy-efficient, low-cost, renewable, and environmental-friendly for a sustainable future. In this section, we highlight the details of these green techniques in gas separation and storage applications. © 2021 Elsevier Ltd.

Düzenli organik kristalin büyütülmesi, alan etkili transistörler veya güneş pilleri gibi gelişmiş organik cihazlar için daha fazla yük taşıyıcı hareketliliği ve daha uzun eksiton difüzyon uzunluğu elde etmenin anahtarıdır. İnce filmlere kıyasla, organik tek kristaller daha düzenlidir. Bu çalışma yenilenebilir enerji alanında ön plana çıkan konulardan biri olan güneş enerjisinde yeni yöntemler arasına giren, organik yarıiletkenlerin tek kristallerin büyütülmesi ve ikili tabaka güneş pillerinde uygulamalarının incelendiği araştırmaları içermektedir. Çalışmada organik malzemelerin tek kristal olarak büyütülmesi, güneş piline uygulanması, karakterizasyonu ve verimlilikleri üzerinde durulmuştur. Farklı inert gaz akış hızı altında fiziksel buhar taşınımı (PVT) ile istenen boyutta ve yüksek kalitede rubren, pentasen ve tetrasen tek kristallerinin büyütülmesi amaçlanmıştır. Bu yöntem, istenen özelliklere sahip tek kristalleri elde etmek için kolay ve kontrol edilebilir bir yöntemdir. Elde edilen tek kristaller,ikili tabaka organik güneş pillerini üretebilmek için PCBM ince filmlerinin üstünde kullanılmıştır. Tek kristaller ve güneş pilleri optik mikroskop, X-ışını kırınımı (XRD), UV-Görünür spektroskopisi, atomik kuvvet mikroskobu (AFM), taramalı elektron mikroskobu (SEM) teknikleri ve güneş simülatörü ile karakterize edilmiştir. Organik yarıiletkenlerin tek kristallerinin büyütülmesinde farklı inert gaz akış hızı kullanılmış ve büyütülen tek kristallerin yapısal ve optik özellikleri üzerine etkileri incelenmiştir. 1,6 L/sa ile 6 L/sa akış hızları aralığında yapılan denemelerde rubren, pentasen ve tetrasen tek kristalleri ile üretilen güneş pillerinin en yüksek enerji dönüşüm verimleri (EDV) sırasıyla %0,34, %0,0197, %0,0151 olarak ölçülmüştür. Üretilen tek kristallerde en yüksek verimlerin kalınlık ve iletkenlik uyumu sonucu elde edildiği belirlenmiştir.Article Citation - WoS: 26Citation - Scopus: 30Nitrogen -Doped Cqds To Enhance the Power Conversion Efficiency of Perovskite Solar Cells Via Surface Passivation(ELSEVIER SCIENCE SA, 2020-08-01) Kırbıyık, Çisem; Toprak, Ayşegül; Başlak, Canan; Kuş, Mahmut; Ersöz, Mustafa[Abstract Not Available]Article Citation - WoS: 8Citation - Scopus: 9Improved Visible Light-Driven Photocatalytic Degradation of Methylene Blue and Methyl Red by Boron-Doped Carbon Quantum Dots(TUBITAK, 2022-01-01) Haspulat Taymaz, Bircan; Kırbıyık Kurukavak, Çisem; Kamış, Handan; Kuş, Mahmut; Taymaz, Bircan Haspulat; Kurukavak, Çisem KırbıyıkThe synthesis of fluorescent carbon quantum dots (CQDs) and their applications have attracted great attention due to their excellent properties. Especially, the unique visible-light absorption and photo-induced electron transfer properties make CQDs available in photocatalytic degradation of organic dye pollutants in water resources. Herein, we synthesized nondoped CQDs and boron-doped CQDs (B-CQDs) by hydrothermal method and compared their photocatalytic degradation activity of methylene blue (MB) and methyl red (MR) dyes under visible light irradiation. The characterization outcomes showed that the optical and structural properties can be easily improved by doping with hetero-atom, thereby photocatalytic performance. As expected, the photodegradation performance of both organic dyes in model solutions by B-CQDs was higher than that of CQDs. MB and MR dyes were photodegraded over 95% by B-CQDs in 90 and 120 min visible light irradiation, respectively. Eventually, the results revealed that nondoped CQDs and B-CQDs are excellent candidates for the degradation of organic dyes because of their high photocatalytic performance under visible light illumination. © 2022 TUBITAK.

The structural and morphological characterization results showed that the optical absorption and film crystallinity can be easily enhanced by B-CQDs additive in P3HT:PCBM solution. Additionally, with the improved crystallinity of P3HT, the effective interchain interaction and phase separation in photoactive layer were achieved. As a result,-50% improving of FF of the device with 5 vol% of B-CQDs additive was determined. Thanks to improved photovoltaic characteristics, best performing device showed a power conversion efficiency of 2.7% (with-50% improve-ment). This report shows that the addition of optimized vol% of B-CQDs into the photoactive blend strongly improves the absorption and leads to achieve efficient charge separation and transport in OSCs.Article Spray Coating Versus Spin Coating of Titanium Dioxide as Electron Transfer Layer for Organic Solar Cells(Springer, 2025-07-05) Yilmaz, Tugbahan; Buyukbekar, Alihan; Kurukavak, Cisem Kirbiyik; Kus, Mahmut; Kırbıyık Kurukavak, ÇisemIn this study, spray coating and spin coating methods for the titanium oxide (TiO2) layer used as the electron transfer layer (ETL) were compared to examine the performance parameters of organic solar cells. Despite the fact that there is no major change in the VOC value, with VOC measured at 0.589 V for the spray-coated device and 0.548 V for the spin-coated device, the device performance parameters of the device fabricated with TiO2 layer sharply increased, with the current density-voltage (J-VSC), fill factor (FF), and power conversion efficiency (PCE) values obtained by the spray coating method. We demonstrate that spray-coated c-TiO2 layers achieve a higher PCE of 2.92% compared to 2.32% for spin-coated devices. The PCE of the solar cell using TiO2 formed by spray coating is 25% higher than the device obtained by spin coating.Article Citation - WoS: 10Citation - Scopus: 12Effect of Different Terminal Groups of Phenyl Boronic Acid Self-Assembled Monolayers on the Photovoltaic Performance of Organic Solar Cells(ELSEVIER, 2021-02-01) Kırbıyık Kurukavak, Çisem; Yılmaz, Tuğbahan; Büyükbekar, Alihan; Kuş, Mahmut; Kurukavak, Cisem KirbiyikHere, a new series of phenyl boronic acid derivative self-assembled monolayers (SAMs) with various functional groups terminated was presented as modification layer for the high performance P3HT:PCBM based organic solar cells (OSCs) with the configuration of ITO/SAM/PEDOT:PSS/P3HT:PCBM/LiF:Al. The photovoltaic device parameters of non-modified and modified ITO surfaces were compared. The electrical and morphologic characteristics of non-modified and modified ITO surfaces were determined by different techniques. It was obtained that the device performances were improved by using all boronic acid derivatives SAM molecules. The best performance of OSC was observed for NO2-PBA SAM modified device, which yielded a power conversion efficiency of 3.17%. Thanks to improved charge transport properties, serial resistance reduced, whereas shunt resistance improved after boronic acid SAMs modification. As a result, it could be said that the using of these SAMs as novel molecules for interfacial modification is an efficient way to improve the device performance of OSCs.Article Citation - WoS: 6Citation - Scopus: 5Modification and Performance Enhancement of P3ht:pcbm Based Organic Solar Cells Incorporated With Phosphorus Doped Carbon Quantum Dots(Elsevier B.V., 2024-06-01) Kırbıyık, Kurukavak, Ç.; Büyükbekar, A.; Tok, M.; Yılmaz, T.; Kuş, M.; Ersöz, M.; Kurukavak, Cisem Kirbiyik; Kırbıyık Kurukavak, ÇisemWe demonstrate a strategy to improve the performance of organic solar cells (OSCs) by phosphorous doped CQDs (P-CQDs). The presence of P-CQDs P3HT:PCBM layer (1 vol% of P-CQDs) enhanced photon harvesting in the UV region and emitting visible light, the PCE was increased from 2.19% to 2.48% and champion device provided a FF of 55.34%. The incorporation of P-CQDs leads to effective photons harvesting ability and collection/transport of charge carriers. The optical absorption and crystallinity of photoactive layer improved with the incorporation of P-CQDs. The larger grain size distribution were obtained with P-CQDs additive helping to better charge extraction. © 2024 Elsevier B.V.Article Performance Improvement Effect of an Inserted Sulfur-Doped Carbon Quantum Dots Layer on Organic Solar Cells(Wiley-VCH Verlag GmbH, 2026-05-01) Tok, Mutahire; Bersani, Massimo; Kurukavak, Cisem Kirbiyik; Kirbiyik Kurukavak, Çisem; Mahmut, K.U.Ş.; Kus, MahmutPoly(3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) based organic solar cells (OSCs) were fabricated and modified with a sulfur-doped carbon quantum dot (S-CQDs) inserted layer on top of the photoactive layer to investigate its effect on devices performance. The surface-engineered S-CQDs synthesized showed strong blue photoluminescence and enhanced UV-vis absorbance in the short-wavelength region, attributed to surface state transitions and band-gap modulation. The results revealed that the light harvesting capabilities were increased by the introduction of the S-CQD layer. Particularly below 450 nm, the absorbance profile broadened without disrupting the characteristic vibronic features of P3HT. The device characterization results demonstrated that an improvement in PCE from 1.76% to 3.07% was achieved owing to improved current density (J SC) and fill factor (FF). With the improved charge extraction and better energy-level alignment at the interface, the increased shunt resistance (R sh) and reduced series resistance (R s) led to an improved FF. Overall, the inserted S-CQDs layer effectively enhanced the optical and electronic properties of the OSCs fabricated, highlighting their potential as an electron transport layer in next-generation organic electronics.Article Gaz Akış Hızının Fiziksel Buhar İletimi Yöntemiyle Büyütülen Antrasen Tek Kristallerin Özellikleri Üzerine Etkisi(2021-01-31) Kırbıyık Kurukavak, Çisem; Polat, Selen; Kurukavak, Çisem KırbıyıkElektronik cihazlar uygulamalarında kullanılan organik yarıiletkenlerin moleküler yapıları ve düzenlilikleri cihaz performansı üzerinde oldukça önemli özelliklerdir.
