Efficient near infrared D-pi-A sensitizers with lateral anchoring group for dye-sensitized solar cells.

A new strategy in which the anchoring group is separated from the acceptor groups of the dyes was developed; among these dyes, the HY103 dye gives a maximum IPCE value of 86% at 660 nm and an eta value of 3.7% in the NIR region reported in DSCs.
