ORGANIC PHOTOELECTRIC CONVERSION DEVICE AND PRODUCTION METHOD THEREOF

摘要

An organic photoelectric conversion device having an anode, a cathode, an active layer disposed between the anode and the cathode, and a hole injection layer disposed between the anode and the active layer, wherein the cathode is an electrode containing an electrically conductive nano-substance, and the hole injection layer is a layer having a residual film rate of 80% or more in measurement of the residual film rate after water rinse treatment.

1. An organic photoelectric conversion device having an anode, a cathode, an active layer disposed between the anode and the cathode, and a hole injection layer disposed between the anode and the active layer, wherein the cathode is an electrode containing an electrically conductive nano-substance, and the hole injection layer is a layer having a residual film rate of 80% or more in measurement of the residual film rate after water rinse treatment shown below:
On a 1-inch square substrate, a film is formed by spin coating so as to give the same film thickness as in the case of film formation as the hole injection layer in the organic photoelectric conversion device, then, a water rinse treatment in which water is placed in the form of meniscus on the film, allowed to stand still for 30 seconds, then, the film is spun at 4000 rpm to fling away water is conducted. The film thicknesses before and after the water rinse treatment are measured by a contact type thickness meter, and (film thickness after water rinse treatment)/(film thickness before water rinse treatment)×100(%) is defined as the residual film rate after water rinse treatment.
