Abstract

The high energy conversion efficiency in the primary photochemistry of natural photosynthesis relies on the unique light-harvesting antenna system spatially separated from the charge generation center and the charge transport pathway, and also on the multiple step electron transfer cascade for the effective charge separation. In this work, we try to develop the fundamental methodologies for the site-specific accumulation of the molecular architectures by using the microphase segregation interface of the normally oriented cylindrical nanostructure as a reliable template, to create the novel photovoltaic devices inspired by the photosystem.
