I am a fifth year PhD candidate in applied physics at Stanford University studing the device physics of organic solar cells with Prof. Michael McGehee and the Center for Advanced Molecular Photovoltaics. Organic photovoltaics offer the potential of providing solar energy at a significantly lower cost than conventional technologies, as they can be mass produced in a fashion similar to newspaper printing and can be made from thin films of abundant, non-toxic materials. Organic solar cells have rapidly improved in efficiency over the last few years and have recently achieved power conversion efficiencies of over 9%. I am particularly interested in understanding the recombination mechanisms which place practical limitations of how much current and voltage can be produced by organic photovoltaics. Prior to Stanford, I have researched light-matter interactions with Eric Mazur's photonics lab at Harvard, granular physics with Heinrich Jaeger at the University of Chicago, and wrote my Masters Thesis on nanoparticle (CdTe)-polymer blend solar cells at Cambridge University with Neil Greenham.
