Research in our group aims to understand the electronic structure of functional materials under various non-equilibrium conditions, such as light irradiation and bias voltage, through computer simulations. We are particularly interested in developing time-dependent optical theories for the modeling of photon-electron interaction, the fundamental driving force for numerous solar energy applications, including solar cells, water splitting and carbon capture. A tangible example is the facilitation of rapid photo-induced charge separation in plasmon-enhanced dye-sensitized solar cells by varying the shape, size, pattern, and composition of the metallic substrate nanoparticles. Another line of our research focuses on the systematic design of photoconductive molecular electronics, a promising single-electron-transport device that may potentially extend Moore’s law for the era of quantum computing. A hybrid DFT/FEM (density functional theory/finite element method) approach is being actively developed to automatically account for the polarization-corrected biased potential for a closed quantum system embedded in an open region of good conductor. In a broader context, the hybrid method can be readily employed to investigate charge migration in any photoelectrochemical system. As a computational chemistry group that enjoys preferential access to some of the world’s fastest supercomputers, we also devote a substantial amount of efforts to implement, optimize and deploy massively scalable quantum mechanics software on a wide range of modern computer architectures.
