Suppressing series resistance in organic solar cells by oxygen plasma treatment
CH Lin, SC Tseng, YK Liu, Y Tai… - Applied Physics …, 2008 - pubs.aip.org
We demonstrate a low series resistance contact of gold (anode)/zinc-phthalocyznine in a
reverse organic photovoltaic device aided by oxygen plasma treatment. The power
conversion efficiency appreciated from 0.2% to 2.13%, post O 2 plasma treatment,
predominantly due to the reduction in the series resistance of the device. A depth profile of
zinc from x-ray photoelectron spectroscopy study revealed a gold layer with graded zinc
composition, instead of pure gold, to be an efficient hole-collector from the organic interface …
