Photovoltaic response of devices with structure of as functions of EBL thickness, where EBL is either BPhen or Yb:BPhen.
Absorption coefficients of BPhen (dashed-dotted line) and Yb:BPhen (dotted line) on quartz substrates. For reference, absorption coefficients of CuPc (solid line) and (dashed line) are also shown.
UPS spectra of a thick film with (a) different BPhen overlayers and (b) different Yb:BPhen overlayers. The coverage (Å) of either BPhen or Yb:BPhen layer is indicated.
Energy level diagram for the and the contacts.
