技術說明

本成果係合成一系列包含予體(donor)及受體(acceptor)的有機雙極性化合物，能夠有效的使用於染料太陽能電池(dye-sensitized solar cells)中作為光敏性之材料。其光電轉化效率(incident photo to current conversion efficiency, IPCE)可達6~7%左右，與目前使用中的釕化合物N719相比，已相當接近。此類新型化合物係由芳香氨基(aromatic amine)的類似物構成的電子予體，與含氰基壓克力酸基(cyanoacrylic acid)類似物的電子受體(Acceptor)隔著架橋(spacer)部分相連接，其架橋部分係由三個芳環組成，如苯環(phenyl)或是塞吩環(thiophene)連接而成。在光電池的結構中，這些化合物利用其端點的酸基(-COOH)吸附在多孔性的二氧化鈦(TiO2)上，形成電池之陽極，加上一價/三價碘離子(I-/I3-)的可逆性氧化還原電解液做為電解質，結合含有鉑電極的導電玻璃，形成一個電子迴路。以此法製成的染料太陽能電池具備成本低、製程簡單及具備可撓性的優點。 This work includes the synthesis of organic dipolar dyes which can be used effectively in dye-sensitized solar cells. These dye compounds contain an aromatic amine moiety as a donor group, a cyanoacrylic acid as an acceptor group, and a spacer made of three linearly connected aromatic rings such as phenyl and thiophene moieties. For the fabrication of a solar cell, these materials were coated onto the surface of porous titanium oxide which works as the anode. A conducting glass containing platinum was used as the cathode, along with an electrolyte containing redox I-/I3- as the charge carriers. These devices exhibit IPCE efficiencies (incident photo to current conversion efficiency) in the range of 6~8%, which are well compatible to the widely used ruthenium complex N719. These materials have the advantages of ready preparation in large quantities at low cost, and the fabrication of bendable cells.
