Description | Internal electric field of the Schottky-barrier solar cells ITO/pentacene/H2-phthalocyanine (H2Pc)/In/Al (cell A) and ITO/H2Pc/In/Al (cell B) was studied by electroabsorption spectroscopy under white light illumination. The H2Pc films in the two cells have different crystal orientations. Under short-circuit condition, the average internal field in the H2Pc layer of cell A is increased by 2.5 times by an illumination of 40 mW/cm2 white light, which is due to a trapping of photogenerated holes and a resulting dipole layer formation at the H2Pc/In interface, while that of cell B is not affected by the white light illumination.
