Development of novel donor and acceptor sam molecules for photovoltaic applications Fotovoltaik uygulamalar için yeni nesil donör ve akseptör kendiliğinden organize tek katman moleküllerin geliştirilmesi

Arkan, Emre

ABSTRACTSurface modification of indium tin oxide (ITO) is a crucial factor to alter the energy level barrier between ITO and perovskite that has direct influence on the charge extraction and recombination at interface. This henomenon has further direct effect on device parameters such as open circuit voltage (VOC), fill factor (FF), and short circuit current density (JSC). This study was base on the synthesis of six novel SAM molecules to be used in fabrication of p-i-n type perovskite solar cells. Since proposed SAMs are of push-pull type molecular nature, contiguous thiophene rings were used ...Daha fazlası

Preparation and characterization of carbon-based nanofluids Karbon bazlı nanoakışkanların hazırlanması ve karakterizasyonu

Fidan-Aslan, Tuğçe

ABSTRACTNanofluids are produced by the addition of nano-sized particles to the base fluid in order to increase the thermal conductivity of heat transfer fluids. Preparation of stable nanofluids with high thermal conductivity is a very complex process and their usage in heat transfer applications are related to many important parameters from the stability of nanofluids to their viscosity. Optimization of these parameters is essential for the practical use of nanofluids. The objectives of this study are to successfully preparecarbon-based nanofluids while investigating the stability mechanisms a ...Daha fazlası

Design and robot operating system based control of a modular robot manipulator Modüler robot manipülatör tasarımı ve robot işletim sistemi tabanlı kontrolü

Kahveci, Aytaç

ABSTRACTIn this thesis, a new design of the modular robot manipulator and its control with Robot Operating System is presented. The modules are designed to have an adjustable twist angle, which enables to create different robot manipulator configurations. Kinematic synthesis on the gripper module is conducted and structural parameters of the gripper is determined. Axis sets on the modules are determined by Denavit-Hartenberg method. Inverse and forward kinematic analysis and singularity analysis are performed. Numerical inverse kinematic solver is proposed for modular robot manipulators with m ...Daha fazlası
