The world’s primary energy source, fossil fuels, is in increasingly short supply. Due to its short supply and high demand, the price of crude oil has risen dramatically over the past several years to the point that it has had a severe impact on some of the world’s economies. Not only is fossil fuel-based energy more costly than ever before, its use also has an extremely detrimental effect on our environment. If the world is to break its dependence on fossil fuels, a new energy source must be found and quickly.
One way to help solve the word’s dependence is to develop a new renewable energy source. This is what many of today’s researchers are working on. The NCHC is devoted to advancing research in this field and ushering in the discovery of new and renewable energy sources. The focus of this project is on the development of an opto-electrical-based renewable energy source. Such a development has great potential as a viable and long-term solution to the world’s energy needs!
The goal of this research is to establish multi-scale computational skills ranging from the nano-meter (i.e. quantum) dimension to the micro-meter (i.e. continuum body) dimension. In this project, we try to integrate the basic opto-electronic (i.e. physical chemistry phenomenon) occurring at the nano-scale level with the transportation phenomenon occurring at the micro-scale level. Then, we try to extend that to the design of the system integration occurring on the device scale (e.g. usually meter scale) level. An example of this is the optimal system design of an opto-electronics system.
Our nano-scale research focuses on two industrial-based renewable energy applications: 1) solar cells and 2) solid oxide fuel cells (SOFC). In this study, we use the first-principle calculation to investigate the photovoltaic mechanism, chemical physics phenomenon, and the transportation phenomenon of these applications.
Regarding SOFCs, we seek to understand the electro-chemical reactions between cathodes and inlet gases which occur at the nano-scale as well as the ion transportation phenomenon in electrolytes occurring at the micro- scale. For this study, we integrate both quantum chemistry (i.e. physics) and molecular dynamics. We also explore new nano-material-based applications such as carbon nanotubes. This recently discovered material shows enormous potential for use in solar cells, SOFCs, flat panel displays, and other electronic devices.
At the continuum body scale, we use optical design tools to develop energy-saving opto-electronic products such as solar condensers and LED-based applications. In addition to being highly functional, optimized optical designs such as high-brightness backlights and brightness enhancing films reduce energy consumption and increase energy efficiency. CADs and other tools are often used to design complex functional optical systems. These tools greatly increase the speed at which a design prototype can be produced.
In this nano-science research, we used both the first principle and molecular dynamics calculations. Currently, we are developing dye-sensitized solar cells, solid oxide fuel cells, and new applications that utilize carbon nanotubes and titanium dioxides.
The current focus of our opto-electrical research is on the design of solar condensers and high-brightness backlight modules (including microstructure distribution and optical film). We also design illumination devices such as LED lens caps and lighting for the automobile manufacturing industry.
