摘要：

Semi-transparent polymer solar cells from a blend of poly-(3-hexylthiophene-2,5-diyl) and [6,6]-phenyl C-61 butyric acid methyl ester (P3HT:PCBM) comprising a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) cathode and a vacuum deposited ndoped organic buffer layer have been realized. Among the investigated organic material systems for n-doping, the use of lithium doped bathophenanthroline (BPhen:Li) allowed for proper energy level alignment and subsequently for an open-circuit voltage V-oc approximate to 600 mV. Upon deposition the PEDOT:PSS adheres selectively on the BPhen:Li buffer layer in order to form the laterally defined transparent cathode. (C) 2009 Elsevier B.V. All rights reserved.
