MgTi2O5 を光電極材料に用いた色素増感太陽電池 -- 分析電子顕微鏡システム利用研究成果、そのXXV(1) -- Dye Sensitized Solar Cell Employing MgTi2O5 as Photoelectrode Material -- Research works accomplished by using Electron Microscope System:XXV(1) -- 鈴木, 健太 Suzuki, Kenta 竹本, 稔 Takemoto, Minoru Dye Sensitized Solar Cell MgTi2O5 Photoelectrode FE-SEM application/pdf Dye sensitized solar cells have been studied and developed extensively by many research groups, because they can be fabricated at lower costs and they show relatively higher power generation efficiency. Anatase-type TiO2 nano-powder is typically employed as a material for the photoelectrode of the solar cell. In the present study, MgTi2O5 nano-powder was substituted for the anatase-type TiO2 nano-powder. It was confirmed for the first time that the dye sensitized solar cell which was assembled by employing the MgTi2O5 photoelectrode really generated electricity. The solar cell showed the open circuit voltage of 0.55 V, the short circuit current density of 0.087 mAcm-2, the maximum power of 0.018 mWcm-2, and 0.38 of the fill factor. The MgTi2O5 film of the photoelectrode had the structure that coarse particles were deposited sparsely, so that the considerably small values of the current density and the power were considered to be accomplished, and. the possibilities of improvement for the power generation properties were shown for the dye sensitized solar cell employing MgTi2O5 as the photoelectrode material. 神奈川工科大学 2015-03-20 jpn departmental bulletin paper VoR https://doi.org/10.34411/00001114 http://hdl.handle.net/10368/31905 https://kait.repo.nii.ac.jp/records/1121 10.34411/00001114 AA12669200 21882878 神奈川工科大学研究報告.B,理工学編 39 5 8 https://kait.repo.nii.ac.jp/record/1121/files/kkb-039-002.pdf application/pdf 1.4 MB 2015-04-30
