Imaging the electric potential within organic solar cells
The charge transport in organic solar cells is investigated by surface potential measurements via scanning Kelvin probe microscopy. Access to the solar cell's cross-section is gained by milling holes with a focused ion beam which enables the direct scan along the charge transport path. In a stu...

| Zusammenfassung: | The charge transport in organic solar cells is investigated by surface potential measurements via scanning Kelvin probe microscopy. Access to the solar cell's cross-section is gained by milling holes with a focused ion beam which enables the direct scan along the charge transport path. In a study of poly(3-hexylthiophene):1-(3-methoxycarbonyl)propyl-1-phenyl[6,6]C61 (P3HT:PCBM) bulk heterojunction solar cells, the open circuit voltage is built up at the top contact. A comparison of the potential distribution within normal and inverted solar cells under operation exhibits strongly different behaviors, which can be assigned to a difference in interface properties. |
