Abstract
In this work, it is intended to study the formation process of ultrathin films by the self-assembly technique, applied on Organic Photovoltaic Devices, particularly those with Bulk Heterojunction Organic Solar Cells (BH-OSC), which has a thin film structure of anode/buffer layer/active layer/cathode. In this study, the employed materials for buffer layer will be polyaniline (PAni) and sul…
