FIG. 1.

Sketch of dominating elementary processes being involved in charge separation at H2TPP/Au junctions under illumination [(1) absorption, (2) exciton formation, (3) exciton diffusion, (4) exciton dissociation, (5) escape of holes, and (6) internal photoemission].

Image of FIG. 2.
FIG. 2.

Surface photovoltage spectra of a -thick H2TPP layer deposited on Au for various modulation frequencies.

Image of FIG. 3.
FIG. 3.

Dynamic photovoltage signal as function of temperature under excitation with a red LED [(a), full triangles] or blue LED [(b), triangles]. The figure also shows the measurements without and with continuous bias light, blue bias LED [(a), full stars] and red bias LED [(b), stars], respectively.
