摘要：

Subporphyrinatoboron(III) (SubB) sensitizers were synthesized for use in dye-sensitized solar cells (DSSCs). The prototype, which comprises a sterically demanding 3,5-di-tert-butylphenyl scaffold, a meso-ethynylphenyl spacer, and a cyanoacrylic acid anchoring group, achieved an open-circuit voltage V-OC of 836 mV, short-circuit current density J(SC) of 15.3 mA cm(-2), fill factor of 0.786, and a photon-to-current conversion efficiency of 10.1%. Such astonishing figures suggest that a bright future lies ahead for SubB in the realm of DSSCs.
