Nanoscale probing of optical and structural properties of polymeric photovoltaic thin films

Herein, we performed a comparative study of bulk heterojunction, bilayer architectures of thin films based MEH-PPV and PCBM dissolved in chlorobenzene. This study aims to investigate the impact of deposition of successive layers on optical characteristics of the active layer. The films were examined using UV-absorption, Photoluminescence X-ray diffraction and Scanning electron microscopy SEM.
