Dye- and Semiconductor-Sensitized Nanoparticle Solar Cell Research at NREL

Research output: Contribution to conferencePaper


The major objective of this research program is to determine the operational characteristics key to efficient, low-cost, stable liquid-junction and solid-state solar cells based on sensitized nanoporous films (in collaboration with DOE's Office of Science Program). Toward this end, we are conducting experimental and theoretical studies to understand the unique physical and chemical factorsgoverning cell performance. Current scientific issues addressed include the influence of film morphology, sensitizer, and electrolyte on the electron transport and recombination dynamics and on the light-harvesting, charge-injection, and charge-collection efficiencies. Recently, we investigated the relationship between (1) transport and recombination, (2) morphological factors of core-shellnanoparticle films and their PV properties, and (3) electron-electron interactions and their effect on the transport dynamics. In this paper, we discuss the connection between transport and recombination and its effect on cell performance.
