In the excited state, an electron is delocalized between these two double bonds. Based on the properties of norbornadiene, we have synthesized a dye carrying a non-conjugated spacer for DSSC application. The components of designed dye include an accepter, a spacer and a donor, with a 3,6-bis(2’-pyridyl)pyridazine skeleton to chelate a varity of metals. Subsequently, we have applied the dye on DSSC device fabrication. Regarding the performance of the cell, the solar energy to electricity conversion efficiency (η) is 0.14% [Voc 4.8 V, Isc 0.47 (mA/cm2), fill factor 0.62].26409074 bytesapplication/pdfen-US非共軛雙鍵π軌域電子未定域化電子隔板配位基光電子轉換效率Norbornadienenon-conjugated double bondsπ orbitalselectron delocalizationspacerligandsolar energy to electricity conversion efficiencythesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/257353/1/ntu-99-R97223183-1.pdf
