| Summary: | 碩士 === 國立中興大學 === 化學系所 === 104 === My thesis is based on mainly two research topics: First synthesis of push-pull porphyrin sensitizers for the application in Dye-sensitized solar cell. Second part covers design and synthesis of electron-rich push-push
porphyrins as the new hole-transporting materials in the perovskite solar cell.I have sensitized different push-pull long alkyl Ortho-substituted porphyrin sensitizers for the application in dye sensitized solar cells. The
newly designed sensitizers consist of various long alkyl chain substituted aniline groups, whereas the acceptor part consist of benzoic acid and 4-(Benzisothiadiazole) benzoic acid as an electron withdrawing anchoring groups. All the synthesized dyes are subjected for device fabrication. For comparison, an efficiency performance of previously published porphyrin sensitizers such as YD2-o-C8, YD2-o-C12, GY30 and GY50 was also evaluated under similar conditions. Detail discussion on the outcome has
been presented in the result and discussion part. In addition, I also found out efficient device conditions, series of anthracene and perylene based D-π-A and D-A-π-A organic sensitizers and the results are presented in result and discussion part. In the another part of my work I synthesized different D-π-D alkyl chain meta-substituted porphyrins for the application as new hole
transporting materials for perovskite solar cells. Research was carried out to help find appropriate dye structure to resolve the problem of stability and cost effect of hole-transporting materials for Perovskite solar cells.
