摘要: Rather strong rectification and photovoltaic effects are observed for sandwich cells in which a thin film (∼3000 A) of metalfree or zinc phthalocyanine is interposed between an ohmic contact (Au) blocking (Al In). The action spectra the short‐circuit photocurrent suggest that only light absorbed near effective producing carriers external circuit. Cells with indium contacts show performance quantitatively consistent presence Schottky junction at contact. quantum efficiency incident on ZnPc phase (In/ZnPc/Au) cell can be as high 14% 6328 A. For actually barrier region, yield approaches unity. efficiencies aluminum 2–3 orders smaller, apparently because insulating layer (∼65 Al2O3 occupies Al/ZnPc junction. This interfacial also affects relation intensity. I...
