Abstract
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 ris selected from h or c-calkyl; ris selected from h, c-calkyl or c-calkoxy; rand rare independently selected from h, c-calkyl, c-calkoxyphenyl or c-calkylphenyl; 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), rand rare independently selected from h, f, c-calkyl or c-calkoxyphenyl; ris 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.
