Solution-processed small molecule:fullerene bulk-heterojunction solar cells: impedance spectroscopy deduced bulk and interfacial limits to fill-factors
Guerrero, Antonio; Loser, Stephen; Garcia-Belmonte, Germà; Bruns, Carson J.; Smith, Jeremy; Miyauchi, Hiroyuki; Stupp, Samuel I.; Bisquert, Juan; Marks, Tobin J. Royal Society of Chemistry (2013)Using impedance spectroscopy, we demonstrate that the low fill factor (FF) typically observed in small molecule solar cells is due to hindered carrier transport through the active layer and hindered charge transfer through ... -
Surface Passivation of Nanoporous TiO2 via Atomic Layer Deposition of ZrO2 for Solid-State Dye-Sensitized Solar Cell Applications
Li, Tina C.; Góes, Márcio Sousa; Fabregat-Santiago, Francisco; Bisquert, Juan; Bueno, Paulo R.; Prasittichai, Chaiya; Hupp, Joseph T.; Marks, Tobin J. American Chemical Society (2009)We report here the utilization of atomic layer deposition to passivate surface trap states in mesoporous TiO2 nanoparticles for solid-state dye-sensitized solar cells based on 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylami ...
