Microscopy Images (IMAGE) Osaka University Caption Time-resolved electrostatic force microscopy images of bilayer organic photovoltaic thin films. The frame step is 300 ns. The movie indicates clearly that the charge generated on a overlayer dissipate and the valley at the edge of the overlayer appears as the time evolution after the pulse light excitation.
