Cuinse2: Electronic Activities Of Grain Boundaries And Solar Cell Fabrication Studies
Erkan, Mehmet Eray (Materials Science & Engineering, 2013-03-20)This dissertation is composed of three studies related to chalcopyrite solar cells. The first study is on electronic activities of grain boundaries (GBs) in CuInSe<sub>2</sub> (CIS). Despite being polycrystalline, chalcopyrite ... -
DNA Based Thin Film As Hole Transport Layer In Bulk Heterojunction Polymer Solar Cells
Kolachure, Vidyalakshmi (Materials Science & Engineering, 2007-09-17)In the field of organic solar cell, the conjugated polymer-fullerene bulk heterojunction concept is one of the ongoing research interests. In this work, the use of de-oxyribose nucleic acid/ hexadecyl trimethyl ammonium ... -
Morphology And Cathode Optimization For Efficient Polymer Bulk Heterojunction Solar Cells
Yang, Yi (Materials Science & Engineering, 2009-09-16)Efficiency of polymer bulk heterojunction solar cell is highly dependent on the active layer morphology and can be controlled by specific experimental conditions. In this work, the influences of P3HT:PCBM blend composition, ... -
Negative Differential Resistance In Hydrated Deoxyribonucleic Acid Thin Films Mediated By Diffusion-limited Redox Reaction
Lee, Hou Kuan (Materials Science & Engineering, 2010-03-03)The charge transport mechanisms in DNA proposed in the literature cover broad range of possibilities including molecular band conduction, superexchange, multistep hole hopping, and polaron hopping. The reason for the ... -
Semi-transparent ZnO:Al/Cu2O Thin-film Heterojunction Fabricated At Low Temperature: Effect Of An Intrinsic ZnO Buffer Layer At The Junction
Huang, Yu-Nung (Materials Science & Engineering, 2012-04-11)The Al-doped ZnO (AZO)/Cu2O semi-transparent heterojunction was realized by an RF sputtering at low temperature in this study. Specifically, the usage of a buffer layer in the junction structure has been found as a key ... -
Solar Selective Optical Coating Made With Metal Nanopaticles For Photovoltaic Thermal Applications
Wang, Xin (Materials Science & Engineering, 2009-09-16)The goal of this research is to fabricate solar selective reflector with suitable optical properties and high thermal and chemical stability for using in the photovoltaic thermal window. While the reflector allows some ... -
Thermally Activated Sulfurization Scheme for CuInS2 Solar Cells
Agrawal, Karan (Materials Science & Engineering, 2008-04-22)Chalcopyrite Solar Cells are now being fabricated on flexible (polymer) substrates. However, CuInS2 solar cells have not been fabricated on the polymer substrates on the commercial scale due the sulfurization temperature ...
