    • The present invention provides organic dyes having a rigid donor and the process for producing the same. The organic dye has the structure of formula (i) or formula (ii), wherein r1 is selected from h or c1-c18 alkyl; r5 is selected from h, c1-c18 alkyl or c1-c18 alkoxy; r6 and r7 are independently selected from h, c1-c18 alkyl, c1-c18 alkoxyphenyl or c1-c18 alkylphenyl; x is selected from any one of the groups represented by formulae (a) to (d); y is selected from a group represented by formula (e) or formula (f); in the formula (e), r2 and r3 are independently selected from h, f, c1-c18 alkyl or c1-c18 alkoxyphenyl; r4 is selected from any one of the groups represented by formulae (g) to (i). The present invention also provides a dye-sensitized solar cell which has a dye layer made from said organic dyes and has a relatively high power conversion efficiency.
    • 本发明提供了具有刚性供体的有机染料及其制备方法。 有机染料具有式(i)或式(ⅱ)的结构,其中r1选自h或c1-c18烷基; r5选自h,c1-c18烷基或c1-c18烷氧基; r6和r7独立地选自h,c1-c18烷基,c1-c18烷氧基苯基或c1-c18烷基苯基; x选自由式(a)至(d)表示的基团中的任一个; y选自由式(e)或式(f)表示的基团; 在式(e)中,r2和r3独立地选自h,f,c1-c18烷基或c1-c18烷氧基苯基; r4选自由式(g)至(i)表示的基团中的任何一个。 本发明还提供一种染料敏化太阳能电池,其具有由所述有机染料制成的染料层,并具有较高的功率转换效率。
