• openAccess   Operation Mechanism of Perovskite Quantum Dot Solar Cells Probed by Impedance Spectroscopy 

      Zolfaghari, Zahra; Hassanabadi, Ehsan; Pitarch-Tena, Didac; YOON, SEOG JOON; Shariatinia, Zahra; van de Lagemaat, Jao; Luther, Joseph M.; Mora-Sero, Ivan American Chemical Society (2018)
      We fabricated perovskite quantum dot solar cells (PQDSCs) and varied the thickness of the QD layer by controlling the number of deposition cycles; the cells were systematically investigated with impedance spectroscopy. ...
    • openAccess   Unraveling Charge Transfer in CoFe Prussian Blue Modified BiVO4 Photoanodes 

      Moss, Benjamin; Hegner, Franziska; Corby, Sacha; Selim, Shababa; Francàs Forcada, Laia; López, Núria; Gimenez, Sixto; Galan-Mascaros, Jose Ramon; Durrant, James American Chemical Society (2019)
      Catalyst modification of metal oxide photoanodes can result in markedly improved water oxidation efficiency. However, the reasons for improvement are often subtle and controversial. Upon depositing a CoFe Prussian blue ...
