Dyes Containing Nucleophilic and Electrophilic Groups (Dyes Containing Nucleophilic Groups and Electrophilic Groups)

摘要

The present invention relates to a dye-sensitized solar cell comprising (i) dye molecules can bond to each other by forming a covalent bond between a nucleophilic group of one molecule and a hydrophilic group of another molecule when the dye is heated, acidified or basicized, and (ii) The present invention relates to a dye comprising a molecule having a nucleophilic group and an electrophilic group, wherein the nucleophilic group is a secondary amino group having no aryl substituent or comprises such a secondary amino group.
