37th GREEN Open Seminar

Conjugated polymer-based solar cells have gained increasing attention as a possible inexpensive source of renewable energy owing to their advantages such as high throughput and large-area production with low-cost printing processes.  To optimize the device performance, the phase-separated nanostructures and local electrical properties of conjugated polymer blends must be characterized since they are closely related to both the generation and transport of charge carriers and thus the overall device performances.  Conductive atomic force microscopy (C-AFM) is a powerful tool for characterizing conductive thin films with a few tens of nanometers resolution.  In this seminar, we will show our recent study on the investigation of nanostructure and local electrical properties of conjugated polymer films by C-AFM.
