Abstract
The aim of this study is to mitigate the loss of performance of organic photovoltaics when the device area is increased. We propose that performance reduction is a result of the poor transverse charge transport due to defects in the electron transport layer and the resistance of the transparent electrode. We modified the surface of a zinc oxide (ZnO) with ethoxylated polyethylenimine and successfully lowered the performance reduction from 30% to 15% based on two electron transport layers of ZnO and ethoxylated polyethylenimine (PEIE)-modified ZnO (ZnO/PEIE bilayer and ZnO:PEIE hybrid layer). We also deposited Ag grids on the indium-tin-oxide (ITO) substrate to facilitate transverse charge transport in the ITO.
