Utilizing first principles Density Functional Theory (DFT), we show that layered inorganic phosphates and tradition organic dyes can be combined to form a new class of bulk heterojunction photovoltaic with high electron and hole mobilities with low exciton recombination, potentially enabling very high efficiency with existing organic-based solar-cell molecules. We will discuss the physical origin of these properties and investigate several approaches for engineering the electronic structure of these materials.
