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.
