Scanning Tunneling Microscopy Investigation of Interfacial Properties between P3HT and PCBM

The electronic structures at the hetero interface of Poly(3-hexylthiophene): methanofullerene (P3HT:PCBM) have a great improvement on the solar cell efficiency due to the formation of bicontinuous nanoscaled phase separation which will enhance charge separation and carrier transport. In the present work, cross-sectional scanning tunneling microscopy and scanning tunneling spectroscopy measurements are utilized to obtain the in-situ atomic-scale band structure across the interface between P3HT and PCBM directly. The distribution of PCBM volume concentration of organic films was also analyzed and discussed in the work.
