Photoinduced electron transfer (PET) from an excited molecule is essential in light energy conversion, such as photocurrent generation. Recently, we achieved atomic resolution in photocurrent measurement by combining a scanning tunneling microscope with a tunable laser. The direction and the spatial distribution of the photocurrent show bias-voltage dependency. By detailed analysis, we succeeded to describe the mechanism based on the molecular orbitals.
