Dye‐Sensitized Solar Cells based on Organic Dual‐Channel Anchorable Dyes with Well‐Defined Core Bridge Structures

Abstract

In stereo, where available: A new approach towards dye-sensitized solar cells is based on dianchoring structural motifs with two donors, two acceptors, and a core bridge donor as a spacer. Their high molar absorption coefficients result in favorable light-harvesting efficiencies for DSSCs based on these dyes. A high conversion efficiency of 4.90 % is achieved when using dye DC4, containing a core bridge carbazole unit, with a multifunctional coadsorbent.
