Summary In this study, symmetric supercapacitors in the form of coin cells were produced by using N‐doped graphene powders as electrode components. Nitrogen‐doped graphene powders were prepared by Yucel's Method with cyclic voltammetry at different potential ranges for selective modification of the powders with functional groups. Electrochemical, spectroscopic, and microscopic characterizations of N‐doped graphene powders were carried out. The formation of graphene layers was supported by scanning electron microscopy and Raman analysis. Functional groups formed on the surfaces of N‐doped graphene powders were determined by X‐ray photoelectron spectroscopy. Specific capacitances of symmetric supercapacitors prepared with N‐doped graphene powders were determined by cyclic charge‐discharge tests. The highest specific capacitance, energy and power values were determined as 235.3 F.g−1, 158.2 Wh.kg−1 and 1760 W.kg−1, respectively.

Summary In this study, Ce/Cr redox flow battery system (RFB), which had redox pair in different oxidation states, was performed in aqueous acidic medium for the first time in the literature. At Ce/Cr RFB system, optimization of acid (H2SO4), and active ion (Cr(III) and Ce(III) ions) concentration were executed by using differential pulse voltammetry and electrochemical impedance spectroscopy methods. The mass transfer type for positive electrolyte was determined by using of cyclic voltammetric method. Both chemical stability and changes on surface morphology of pencil graphite electrode were analyzed with scanning electron microscope. Cyclic charge/discharge test was performed for this novel electrolyte composition. Cell potential and the highest discharge capacity values were also determined as 1.52 V and 21.2 mAh L−1, respectively, at 0.8 mA cm−2 charge current density and 0.2 mA cm−2 discharge current density. Obtained data in this work can open a new perspective for the using of the alternative redox couples for the redox flow batteries.

“…Perovskite solar cells can be fabricated in two different configurations of n-i-p or p-i-n. n-i-p configuration consists of an electron transport layer (ETL), perovskite semiconductor material, and a hole transport layer (HTL) whereas in the p-i-n, which is also regarded as inverted type perovskite solar cells, a hole transport layer, perovskite layer and an electron transport layer are employed. P-i-n structures serve several advantages such as lower processing temperatures and the use of well-known fullerenes as electron transport layers [12][13][14]. In the p-i-n structure, nickel oxide (NiOx) received very much attention among researchers since NiOx provides good stability and possesses high hole mobility [15][16].…”

Abstract. Bathocuproine (BCP) (2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline) is a well-known material that is employed as a hole-blocking layer between electron transport layer (ETL) and metal electrode in perovskite solar cells. It has been demonstrated that the use of BCP as a buffer layer between the ETL and the metal electrode in perovskite solar cells is highly beneficial. In literature, BCP is coated using vacuum processing techniques. Vacuum processing techniques require more energy and cost-effective processing conditions. In this work, we used BCP layers processed through wet processing techniques using sol-gel method with different concentrations. We achieved a short circuit current density (Jsc) of 16.1 mA/cm2 and an open circuit voltage (Voc) of 875 mV were acquired and a fill factor (FF) of 0.37 was calculated for perovskite solar cells without a BCP layer leading to a power conversion efficiency (PCE) of 5.32 % whereas Jsc of 19 mA/cm2, Voc of 990 mV were achieved and a FF of 0.5 was calculated for perovskite solar cells employing BCP layers with concentration of 0.5 mg/ml and spin cast at 4000 rpm, leading to a PCE of 9.4 %. It has been observed that the use of a BCP layer with an optimized concentration led to an improved device performance with an increase of 77 % in PCE in ambient air under high humidity conditions for planar structure perovskite solar cells in the configuration of ITO/NiOx/MAPbI3/PCBM/BCP/Ag. Resumen. Batocuproina (BCP) (2,9-dimetil-4,7-difenil-1,10-fenantrolina) es un material que se emplea como capa de bloqueo de huecos entre la capa transportadora de electrones (ETL) y el electrodo metálico en celdas solares basados en perovskitas. Se ha demostrado que el uso de BCP como capa amortiguadora entre el ETL y el electrodo metálico en las celdas solares de perovskita es beneficioso. Comúnmente el BCP se recubre mediante técnicas de procesamiento al vacío, las cuales requieren altos costos energéticos. En este trabajo utilizamos capas de BCP procesadas mediante técnicas de procesamiento húmedo utilizando el método sol-gel. Logramos una densidad de corriente de cortocircuito (Jsc) de 16.1 mA / cm2 y un voltaje de circuito abierto (Voc) de 875 mV y se calculó un factor de llenado (FF) de 0.37 para las celdas solares de perovskita sin una capa de BCP lo que conduce a una eficiencia de conversión de energía (PCE) de 5.32%. Para celdas solares de perovskita que emplean capas de BCP con concentración de 0.5 mg/ml y centrifugado a 4000 rpm el valor de Jsc fue de 19 mA / cm2, se lograron Voc de 990 mV y se calculó un FF de 0.5, lo que lleva a un PCE del 9,4%. Se observó que el uso de una capa de BCP con concentración optimizada puede conducir a un rendimiento mejorado del dispositivo con un aumento del 77% en PCE en el aire ambiente, en condiciones de alta humedad, para celdas solares de perovskita de estructura plana en la configuración de ITO / NiOx / MAPbI3 / PCBM / BCP / Ag.
