Outline of Final Research Achievements |
We synthesized magnesium porphyrin derivatives as electron donors used for small-molecule solution-processable organic thin-film solar cells. Especially, we synthesize these derivatives by using two or four diketopyrrolopyrroles (DPPs) organic dyes connected to the porphyrin cores through triple bonds. In bulk heterojunction organic thin-film solar cells using these porphyrins as electron donors and fullerene derivatives as electron acceptors, we achieved 7.40% power conversion efficiency. We also revealed that magnesium porphyrins have higher solubility and longer excitation lifetime than zinc congeners.

Academic Significance and Societal Importance of the Research Achievements |
自然界でも光合成で用いられるマグネシウムポルフィリノイドを人工的な太陽電池で用いることの有用性を示すことができた.これにより,軽量でフレキシブルな有機薄膜太陽電池に,自然界でも用いられている物質を光電変換材料としてを適用することへの道筋をつけた.環境に優しい有機色素を用いた有機薄膜太陽電池が実用化されれば,環境や景観への負担が少ない発電施設やIoTなどの自立電源へ利用されるものと期待される.
