Organic dyes having rigid donor, process for producing the same, and dye-sensitized solar cell

摘要

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.;
