Internships

Alexa Krakaris ’12

During this summer internship I worked with Robert Street conducting research ­pertaining to organic photovoltaics. I conducted various experiments designed to study the ­effect of varied temperature annealing on the behavior of organic solar cells. I analyzed these results and compiled a comprehensive set of data, graphs, and spread sheets. Our ­research supported the theory that an exponential energy band tail exists, which reflects the physical properties of the organic material. We hope that this research will lead to further development in the field of organic photovoltaic devices and an overall increase in their efficiencies.
