The goal of this proposal is to provide theoretical foundations for electronic correlation effects in molecular and nanostructured systems under non-equilibrium conditions designed for solar and chemical energy production. More specifically, I will focus on correlation effects that involve electronic interactions competing with other types of interactions with e.g. Bosonic degrees of freedom that cause attractive forces. A central understanding of the competing interactions and fluctuations in molecular systems will be used to investigate transport properties of molecular junctions, considering e.g. charge, spin, and heat trans- port. Special attention will also be devoted to noise spectroscopy of such systems, which is a technique that can be successfully employed to determine excitation spectrum in quantum fluctuating entities. Those investigations are extremely pertinent since the performance and functionality of molecular electronic devices strongly depend on the excitation spectrum. All considered effects, correlation and inelastic, will be considered under non-equilibrium conditions since any type of molecular electronics device designed for energy production, or energy conversion, is by construction in a non-equilibrium configuration.
