This program was directed at demonstrating functional optoelectronic devices by contacting individual, highly photoactive molecules of biological origin. This 2 phase program each phase duration of 1 year, successfully addressed the fundamental engineering issues associated with the application of proteinmolecular aggregates to electronic devices purification of the complexes, and their interconnection to conventional bulk organic circuitry. We have demonstrated a molecular power source using a single antenna complex extracted from a biological photosynthetic unit. To exploit the optimization of photosynthesis, we have demonstrated, for the first time, the solid state integration of photosynthetic complexes in solar cells. The internal quantum efficiency of the first generation of devices is estimated to be 12.
