This science café will feature a hands-on solar energy conversion activity in which participants will create their own solar cell using blackberry juice and titanium dioxide nanoparticles. Participants will construct the solar cell and test it’s efficiency. The activity is one that many area high school science students have already participated through an outreach program called “Juice from Juice” which instructs students and teachers the advantages of nanotechnology and how it is applied to develop inexpensive solar energy technologies. This outreach is activity is also connected to my research efforts at UNC Charlotte to design the next generation of molecular sensitizers for solar energy conversion applications. In particular, we are interested in designing new molecular sensitizers (called porphyrins) that mimic chlorophyll molecules in nature. A key component of this research is uncovering how excited state energy (called excitons) move from molecule to molecule in the same way light energy is absorbed and converted into usable energy in photosynthesis. Ultimately, our efforts are geared towards using these systems in solar cell devices to generate electricity, or in a photoelectrochemical device that can produce hydrogen fuel using only sunlight and water.
Parking is across the street from the center city. Parking is covered by CASN. A parking pass will be emailed upon sign up. If walk-in day of event, parking passes will be available at UNC Charlotte Center City front desk.
