Book Description
Abstract: Over the past two decades, earth has witnessed a seminal growth in the global energy consumption rates accompanied by drastic Carbon dioxide emissions in the atmosphere. Recent callings for sustainable energy systems that can offset the carbon footprint made it inevitable to develop technologies that provide clean fuel alternatives to fossil fuels. Hydrogen can be that alternative as it is an it only produces water as a byproduct during combustion. However current commercial hydrogen production practices are energy consuming, and get their energy from fossil fuels. Solar energy, can be harvested with semiconducting materials. Consequently, it became of great necessity to develop semiconducting electrodes that can efficiently convert solar energy to electrical energy used in the splitting of water for the production of hydrogen. In the first part of this thesis, earth abundant metal, Titanium (Ti), was used to design electrodes that provide the reaction surface upon which water is split into Hydrogen. On a different note, the current commercial energy storage devices still face performance limitations, have high maintenance cost, and are not eco-friendly. Electrochemical supercapacitors hold the potential of being the next generation of efficient and clean energy storing devices. Their fast charge/discharge rates make them the perfect storing devices for peak power delivery applications contrary to batteries. However, supercapacitors are still underdevelopment and face major challenges such as relatively low energy density, performance degradation, and high cost. In order to overcome these limitations a lot of research is carried on the design of efficient, cheap, and stable electrode materials. The emergence of transition metal oxides as an active material for solar cells have encouraged the research of using them as electrode materials for supercapacitors. New strategies are developed for the fabrication of nanostructured mixed oxides fibers, incorporated with carbon based materials. These methods are expected to improve the capacitive performance and cyclic stability of the metal oxides electrodes. In the second part of the thesis, we propose a synthesis route for the fabrication of binder-free Manganese and Vanadium mixed oxides nanofibers electrodes for supercapacitors.

Book Description
Developing sustainable energy is one of the most pressing issue in modern society. Solar energy is clean and abundant. It is the champion of energy resources. However, we derive less than 1% of the total consumed energy from the sunlight. The huge gap between the solar energy we utilize every year and the tremendous undeveloped potential energy from sunlight presents significant challenges. To increase solar energy utilization, an efficient and convenient energy flow path is required. This dissertation presents an energy flow path for solar energy utilization. Solar energy is first converted into electricity using solar cell devices. Due to the intermittent nature of solar energy, the converted solar electricity needs to be integrated with energy storage systems. An electrochemical fuel is employed to store the converted solar electricity through a semi-flow battery. The electrochemical fuel can be transported and distributed to end users, and applied in electric vehicle applications through a refillable battery. The refillable battery can be "recharged" not only by solar electricity like conventional batteries, but also by refilling the electrochemical fuel. It offers a fast driving range extension method to effectively remove the main barriers in the broad adoption of electric vehicles, which in the meanwhile decrease energy dependence on finite fossil fuels in the transportation sector. In developing this solar energy flow path, we studied ultra-thin single-crystalline Si solar cells and transparent conducting electrodes in the solar to electricity conversion part. Recently, there is a strong trend to develop ultra-thin single-crystalline Si solar cells because of their lightweight and flexible form factor. Thin Si, however, absorbs less light, which means that an effective light trapping scheme must be used to improve light absorption in thin cells. Light trapping design using double-sided nanocone array surface textures were studied in this work, presenting very effective light absorption enhancement. Moreover, the processability of the ultra-thin Si in solar cell fabrication is also demonstrated. Besides crystalline Si technology, another major type of solar cell technology is thin film solar cells, where transparent conducting electrodes serve as essential components. In this work, we also demonstrate a hybrid concept for transparent conducting electrodes, which improves the performance of the existing technologies by several orders of magnitudes. In the solar electricity storage part, robust integrated system of solar module and Li/polysulfide semi-flow battery were studied, showing a high round-trip efficiency of 12%. The polysulfide material can be considered as an electrochemical fuel, charged by solar electricity, stored in external tanks, and then applied in a refillable battery to power electric vehicles. The low-lost refillable Li/polysulfide battery shows good rate capability and temperature performance, which are both very important factors for electric vehicle applications.
