Efficiency enhancement of polymer photovoltaic devices hybridized with ZnO nanorod arrays by the introduction of a vanadium oxide buffer layer
K Takanezawa, K Tajima, K Hashimoto - Applied Physics Letters, 2008 - pubs.aip.org
The introduction of an electron-blocking layer of vanadium oxide between the organic layer
and the Ag electrode was studied as a means of improving the performance of bulk
heterojunction photovoltaic devices based on poly (3-hexylthiophene):(6, 6)-phenyl C 61
butyric acid methyl ester hybridized with vertically aligned ZnO nanorod arrays. The power
conversion efficiency was further improved to 3.9% by applying a short circuit current density
of 10.4 mA cm− 2, an open circuit voltage of 0.58 V, and a fill factor of 65% under AM1. 5 …
