The Center for Functional Nanomaterials (CFN) at Brookhaven National Laboratory is a science-based user facility devoted to nanotechnology research addressing challenges in energy security. The five internal research groups – Electronic Nanomaterials, Catalysis/Surface Science, Biology/Soft Materials, Electron Microscopy, and Theory/Computation – accompany a broad portfolio of scientific capabilities and an active external User program.
Our research program in Electronic Materials incorporates nanostructured materials with precisely defined and tunable internal dimensions as experimental platforms for understanding and improving the three critical steps of photovoltaic energy conversion: solar light absorption by the active photovoltaic material; dissociation of photogenerated electron-hole pairs into free charge carriers; and charge collection.
Nanometer-scale polymer self-assembly has applications in both today’s and future technology. I will present thoughts and preliminary experimental results showing the promise of self-assembling materials for improving photovoltaic device performance, while at the same time framing the discussion around our prior successful implementation of self-assembly processes in high-performance semiconductor devices.
