Recently, dye-sensitized solar cells (DSCs) were shown to be the highest power conversion efficiency technology of any solar cell technology when using photons from the beginning of the solar spectrum until 700 nm. Two key directions are apparent in further elevating this technology: (1) broadening the spectral window used, and (2) efficiently subdividing the spectrum further for multijunction devices which can be used in combination with many solar cell technologies. Progress toward designing optimal panchromatic organic sensitizers to use NIR photons based on physical organic concepts such as proaromaticity and cross conjugation will be discussed. Additionally, the design and realization of a series sequential multijunction dye sensitized solar cell (SSM-DSC) system for effective photon management will be discussed. Ongoing research to optimize this system based on transition metal redox shuttle design and high voltage organic dye design will be analyzed. The SSM-DSC system coupled with electrocatalysts as solar-to-fuel systems has been shown to power water splitting and CO2 reduction coupled with water oxidation from a single illuminated area without external bias.

Jared Delcamp joined UM as an Assistant Professor in the Department of Chemistry and Biochemistry after completing two post doctoral fellowships (Swiss Federal Institute of Technology, Lausanne and Georgia Institute of Technology) with a focus on chromophore design, organic-inorganic interfacial charge separation, dye-sensitized solar cell fabrication, and the synthesis of air-stable high energy electron transfer reagents. He earned his Ph.D. from the University of Illinois Urbana-Champaign in 2010 with a thesis focused on the palladium catalyzed oxidative Heck reaction. Jared holds a Chemistry B.S. degree from the University of Kentucky where he co-authored 6 manuscripts as an undergraduate on organic light emitting diode materials. He has authored >40 publications with >20 as an assistant professor and is the co-inventor for 5 awarded patents and 3 pending patents.
