All the students chose to do live demonstrations at the Museum of Science for their projects.
These photos were taken during the development process while the students were creating their hands-on activities during the January internship.
These are photos of the students demonstrating their hands-on activities with museum visitors. Lei Sun developed a hands-on activity about how mobius strips can represent the movement of electrons in Topological Insulators; Tian Ming developed a hands-on activity about how cell phone displays work; Tom Mahony developed a hands-on activity about polarized light and lasers; and Nadav Geva developed a hands-on activity about electron-hole pairs.
These are photos of students learning how to deliver hands-on activities and practicing with museum visitors.
The mission of the Center for Excitonics is to develop the science and technology of excitons, to reveal the fundamental characteristics of these crucial quasi-particles, and enable new solar cells and lighting technologies.
Our efforts are divided into three major thrusts. Each thrust is comprised of seven to ten faculty devoted to key scientific problems confronting the development of more efficient solar cells and solid state lighting.
When a chlorophyll molecule in the leaf of a plant absorbs a photon of sunlight, the solar energy is converted into an excited state of the molecule known as an exciton. The exciton then transports the energy between molecules in the leaf, and ultimately mediates the conversion of sunlight into electrical energy.
Thus, excitons are packets of energy confined within a material. They are the crucial intermediate for energy transduction in all kinds of low-cost electronic materials. Excitons also dominate the behavior of disordered synthetic nano-materials like polymers and inorganic quantum dots. Consequently, excitons control solar energy conversion in low-cost solar cells, and also light emission in organic and quantum-dot based LEDs.
