Paul Hoertz's Experience
Nonprofit; 1001-5000 employees; Research industry
January 2009 – Present (5 years 9 months) Research Triangle Park, North Carolina
Research Chemist. Serves as PI and project manager on several energy-related projects, including the RTSFI, the UNC-EFRC, and ARPA-E Electrofuels. These projects focus on the development, characterization, testing, and optimization of porous, high surface area particle films for application in various energy conversion devices including dye-sensitized photoelectrochemical (DS-PEC) solar fuel devices, dye-sensitized solar cells (DSSCs), hybrid inorganic-organic photovoltaics, and electrolyzers. Serves as a Technical Contributor on SSL, nanofiltration, cementitious materials, nanofiber processing, and nano-informatics projects.

February 2007 – January 2009 (2 years) Chapel Hill, North Carolina
Postdoctoral Associate (Advisors: Thomas J. Meyer, Wei You). Developed DS-PECs consisting of surface-bound molecular chromophores and catalysts bound to mesoporous nanocrystalline films. Developed synthetic methods for preparing high surface–area tin-doped indium oxide (ITO) nanoparticle films for electrochromic, electrocatalytic, and solar cell applications. Created unique surface-bound layer-by-layer energy transfer antennae structures for DS-PEC and DSSC applications. Optimized bulk-heterojunction thin films and device architectures for polymer-based organic photovoltaics and designed and fabricated organic spintronic devices based on self-assembled monolayer molecular junctions.

November 2003 – January 2007 (3 years 3 months)
Postdoctoral Associate (Advisor: Thomas E. Mallouk). Developed a synthetic procedure to produce novel, non-aggregated 2 nm iridium dioxide (IrO2) water oxidation nanoparticle catalysts with surface-bound visible light absorbing ruthenium(II) (Ru II) polypyridyl complexes for integration into DS-PEC water-splitting devices. Developed synthetic methods and processes for preparing TiO2 nanoparticle thin films which reliably gave record high-efficiency (>10%) DSSCs. Developed inverse opal photonic crystals to manipulate light propagation in DSSCs and designed, constructed, and tested novel tandem DSSC-silicon solar cells. Gained extensive experience with materials characterization, including transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), and X-ray powder diffraction (XRD).

Paul Hoertz's Education
PhD, Inorganic/Materials Chemistry
1998 – 2003
Research Associate (Advisor: Gerald J. Meyer). Discovered a unique charge separated state in dye-sensitized titanium dioxide (TiO2) nanocrystalline thin films from excited-state electron injection followed by subsequent electron trapping on ground state sensitizers. Optimized excited-state properties of molecular dyes to control rates and quantum yields of electron injection and other electron transfer processes in DSSCs. Gained skills in DSSCs, surface chemistry, electron transfer kinetics, energy transfer, photoelectrochemistry, spectroelectrochemistry, sol-gel metal oxide nanoparticle synthesis, and nanosecond transient absorbance and photoluminescence spectroscopies. Synthesized and characterized various compounds, including ligands for Ru(II) coordination compounds, Ru(II) heteroleptic compounds, and organic surfactants.
1994 – 1998
Performed undergraduate research on Surface Enhanced Raman Spectroscopy with John J. McMahon
