| Outline of Final Research Achievements |
We tried to fabricate new type of organic thin-film solar cell using triplet triplet annihilation (TTA) photon energy upconversion. At first, the upconversion luminescent nanoparticles based on TTA were successfully prepared by coloading sensitizer (octaethylporphyrin Pd complex) and annihilator (9,10-diphenylanthracene) into silica nanoparticles. But, the organic thin-film solar cell mixed this silica nanoparticle was very high resistance and we couldn’t observe the upconversion luminescent. The reason of the results is caused by an aggregation of the silica nanoparticles.
To prevent the aggregation of silica nanoparticles, we used the microphase-separated nanostructures by block copolymer. We synthesized the new block-copolymer having poly(4-vinylpyridine). The spin-coated film of the block copolymer was hexagonally arranged. The P4VP cylindrical microdomains were perpendicularly oriented to the substrate.
