| Outline of Final Research Achievements |
We have confirmed the phenomenon of obtaining higher current density and quantum yield than using standing waves at a film thickness of 500 nm or more, which is thicker than the optimum value for polymer systems, by crystallizing the photoelectric conversion layer of ZnPc:C60, a standard material bends for small molecule donor:acceptor systems, which was conventionally considered disadvantageous for thicker films than 100 nm. The main purpose of this study was to apply this phenomenon to various material systems, and to demonstrate it even for materials that exhibit higher photoelectric conversion efficiency.
As a result, although higher current densities could not be obtained, similar trends were confirmed for many donor materials. In addition, we were able to select new small molecule-based acceptor materials for future application of this technique.
