SNOM measurements performed on the active layer-electron transport layer interface in OPV device

 

Images obtained in SNOM Reflection mode at the interface between the active layer and the electron transport layer for a ZnO NPs/94% P3HT+6%SWCNT/PEDOT-PSS/ITO organic solar cell developed in our lab.
