Increasing demand and high consumption of energy lead the researchers to think about the alternative renewable and sustainable source that could fulfil the energy requirement. For this purpose smooth transition to renewable technologies are necessary. There are several alternative technologies available, among them Dye Sensitized Solar Cell (DSSC) can be the promising one. DSSC has achieved around 12% power conversion efficiency, hence improvement is possible if new materials are synthesized. Our study aims to synthesize and characterization of novel isomerically pure perylene-3,4,9,10-tetracarboxylic acid derivatives that are promising family of organic dyes as light harvesting material (sensitizer). The study involves the synthesis of novel antisymmetric compounds and investigation of their structural, and photo-physical properties. This work demonstrates that perylene tetracarboxylic ester unit is a versatile building block for the synthesis of variety of light harvesting systems. The resulting compounds are soluble in variety of organic solvents, and show broad absorption bands extending up to near infrared region.

Synthesis of some metalophthalocyanines and their effects on the performance of pem fuel cells Erkan, Serdar; Eroğlu, İnci; Department of Chemical Engineering (2005) Importance of clean, sustainable and renewable energy sources are increasing gradually because of either being environmental friendly or being alternative for fossil fuels. Hydrogen energy system will let the utilization of alternative energy sources. Fuel cells are the most suitable energy conversion devices while passing through the hydrogen economy. The cost of the fuel cell systems need to be reduced in order to achieve commercialization of these systems. One of the most important cost items is platinum...
Synthesis and characterization of nickel zinc oxide nanoparticles and their investigation as water oxidation catalyst Ağcalı, Rahime Yağmur; Nalbant Esentürk, Emren; Department of Chemistry (2020-10) The depletion of fossil fuels has steered attention to discover new energy sources. Fossil fuels are not desirable to use because of their hazardous effects on earth and being non-renewable, yet they have been used as primary energy sources all over the world. Due to their limited amount, the focus of research has become maintaining renewable, green, and clean energy. In this sense, among others hydrogen has a great potential for being a primary source. The possible supplied energy from hydrogen is gr...
Synthesis of first row transition metal oxide nanomaterials for electrocatalytic water oxidation reaction Çetin, Asude; Nalbant Esentürk, Emren; Department of Chemistry (2020) Environmental concerns associated with the use of fossil fuels have elevated the demand for safe, clean and renewable energy sources. Hydrogen is an outstanding energy carrier because of the high amount of energy stored in its bond, and an excellent alternative to fossil fuels. Therefore, production of hydrogen from readily available and abundant sources such as water through electrochemical water splitting has gained increasing attention in the last couple of decades. However, water oxidation step of overa...
Synthesis of bistriphenylamine and benzodithiophene based random conjugated polymers for organic photovoltaic applications Çetin, Aslı; Çırpan, Ali; Department of Chemistry (2018) Nowadays, traditional fossil fuels have become unable to compensate huge energy demand of the world due to the population increasing day by day and bringing about destructive greenhouse effect. Owing to all of these problems, renewable energy sources such as solar energy not only can be candidate for the solution of this expanded energy need but also can protect the earth by reducing the production of greenhouse gas. In this study, electronic, optical features and photovoltaic applications of two novel orga...
CHARACTERIZATION OF LATENT THERMAL ENERGY IN A STORAGE UNIT WITH FIBONACCI-SEQUENCE-INSPIRED FINS Baghaei Oskouei, Seyedmohsen; Bayer, Özgür; Department of Mechanical Engineering (2023-1-19) Latent thermal energy storage (LTES) is a viable method to mitigate one of the main problems with renewable energy sources, such as solar energy, which is their intermittent nature. LTES units take advantage of the large latent heat of fusion in phase change materials (PCMs) to store a substantial amount of energy in a relatively small volume, making them efficient and economical. The major challenge with PCMs is their low thermal conductivity, eventuating long melting (charging) and solidification (dischar...
