Abstract

Herein we report the evaluation of a PAni:PSS Layer-by-Layer (LbL) ultrathin film as hole transport layer (HTL) of Bulk Heterojunction Organic Solar Cells (OSC). It was also highlighted the importance of using a lithium fluorite (LiF) dielectric layer to improve devices overall performance. The best result was found for devices comprising five PAni: PSS bilayers and a LiF dielectric layer in a thin film structure. There is a perspective of increasing device's efficiency based on LbL materials used as HTL and their deposition parameters. (AU)
