Dye‐Sensitized Solar Cells Based On Donor–Acceptor π‐Conjugated Fluorescent Dyes with a Pyridine Ring as an Electron‐Withdrawing Anchoring Group

Abstract

Firmly attached: The short-circuit photocurrent density and conversion yields of solar cells based on pyridine-containing donor–acceptor π-conjugated (D-π-A) dyes (see scheme) are greater than those for conventional D-π-A dye sensitizers that bear a carboxy group as the electron-withdrawing anchoring group. The dyes are attached to the surface by coordinate bonding with the Lewis acid sites of TiO2. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
