In less than one hour, enough solar energy is absorbed by Earth’s atmosphere, oceans and land masses to match the total amount of energy consumed by humans in one year.
Such a vast energy resource has stimulated a tremendous impetus to develop efficient light harvesting technologies. As a result, a growing array of device types have emerged from photovoltaic research and, in recent years, there has been a growing focus on developing quantum dot and nanocrystal-based devices for light harvesting applications.
Fundamental interest in quantum dot light harvesting stems from the fact that their band gaps can be tuned by changing particle size and shape.
Furthermore, quantum dots are resistant to photo-bleaching; their solution phase syntheses are robust with good size and shape selectivity; and they can support multiexcited states, with potential importance for optoelectronic applications.
In the Nanoscale Dynamics Group we are interested in the fundamental processes that control the interaction of quantum dot excited states with their surroundings.
Using a combination of synthesis, spectroscopy and semi-empirical data analysis we are trying to understand the dynamic interactions that link photoexcited quantum dots with local electronic states including, e.g., surface traps, coordinating ligands, surface plasmons, and other quantum dots.
Ultimately, our results will be used to create new quantum dot materials with greatly improved characteristics for light harvesting applications.
