The surface of polymer solar cells is soft and sticky
which affect the scan of AFM tip seriously and influence AFM observation. In this study
tapping mode
ScanAsyst mode and FastScan mode were used to analyze the morphology and phase separation of polymer solar cells. And the effects of scanning parameters
such as types of tips
control of interaction force between sample and tip and scan rate were discussed. Results demonstrate that AFM tips with low elastic coefficient and reflective coating are good for the detection of polymer solar cells. And it is very helpful to control low interaction force. In addition
high scanning rate is not favorable for getting good morphologic image
thus the scanning rate should be controlled. It is important to select appropriate parameters and imaging mode in characterization of polymer solar cells.
