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

Bayram, Abdullah

ABSTRACTEnvironment and health is two important things that are so important to human lifebecause they cannot be separated from each other. The problems related with thesetwo events will negatively affect human life. Therefore, health and environmentalproblems should be monitored with proper testing devices and analyzed. In order toperform these tests, we need cheap, reliable and fast test equipment. With therevolution of three-dimensional (3D) printing technology that is cheap, practical, fastmethod of production, this kind of test devices can be produced. This productionmethod is used to pro ...Daha fazlası

Fabrication of hysteresis-free perovskite solar cells by SAM modified electrode SAM modifiyeli ITO elektrot ile histeresis östermeyen perovskit güneş hücresi üretimi

Yalçın, Eyyup

ABSTRACTEnergy has become one of the main problems of humanity after the industrial revolution and the rapid rise in world population. Most energy resources depend on fossil fuels, which causes environmental problems. Solar energy is a clean and sustainable alternative to the increasing world energy demand. In this context, perovskite solar cells (PSCs) are particularly attractive due to ability to achieve very high efficiencies. The power conversion efficiency (PCE) of PSCs has rapidly grown from 3.8 in 2009 to over 25.5 in 2022, which making it fastest advancing solar cell technology to date ...Daha fazlası

Surface modification of micronized quartz powders and investigation of additives as filling material in polymer matrix composite materials Mikronize kuvars tozlarının yüzey modifikasyonunun yapılması ve polimer matrisli kompozit malzemelerde dolgu malzemesi olarak incelenmesi

Akyüz, Orhan

SUMMARYThe interfacing compatibility of the matrix material with the filler material in composite materials is one of the most important factors affecting the performance of the composite. A wide variety of chemical methods are applied to increase the interfacial compatibility of the matrix material with the filler material. The most important of all is the surface modification technique, in which surface-active agents are used to reinforce the matrix-filler bond and where a chemical process is applied to the surface of the filler material.This technique is based on the chemical treatment of t ...Daha fazlası

Manufacturing and characterization of thermal conductive polymeric composite materials Termal iletken polimerik kompozit malzemelerin üretilmesi ve karekterizasyonu

Kaya, Nusret

ABSTRACTElectronic industry is growing dramatically in the last quarter of the century. Recent advances in electronics industry enable the miniaturization of micro transistors and the integration of more transistors into the electronic devices, resulting in a higher performance device. However, this condition increases the heat flow in the electronic devices. The performance of electronic devices depend on the working temperature, for this reason, it is important to remove the heat produced in the device as fast and efficiently as possible in order to hold the system temperature of the electro ...Daha fazlası
