important sustainable issue of human society. Among a variety of renewable energies such as wind, biomass, hydroelectric power, and geothermal power, solar energy is the most abundant candidate that provides 1.7 × 10 5 TW of energy striking the surface of the Earth annually. [1] To date, crystalline silicon solar cell is the most mature photovoltaic (PV) technology with power conversion efficiency (PCE, η) over 25%. However, the long energy payback time, energy-intense manufacturing process, and recycling problem of siliconbased solar cells remain critical issues for sustainability. [2] In 1991, Grätzel reported a new type of PV techniques, dye-sensitized solar cells (DSSCs), which have several advantages such as low-cost fabrication, colorfulness, flexibility, and high efficiency under dim light than silicon-based solar cells. [1a,3] These features make DSSCs a promising technology for applications in building-integrated photovoltaics (BIPV) and portable electronic devices. [4] To improve the PCE and stability of DSSCs for commercialization, considerable efforts have been devoted to the research of conductive electrode materials, [5] semiconductor nanoparticles, [6] dyes, [7] electrolytes, [8] and catalytic counter electrode. [9] In addition, the redox shuttle of electrolytes strongly influences the photovoltage of the DSSC. The theoretical maximum open circuit photovoltage (V OC ) can be as high as 1.37 V for DSSCs using [Cu(tmby) 2 ] 1+/2+ as the electrolyte. [10] These approaches have shown that the dye plays an important role in DSSCs by governing incident light harvesting and electron injection to photoanode. Compared to other types of dyes such as ruthenium complexes, nature pigments, and organic dyes, [7a,11] porphyrins have several advantages including intense absorption in the visible region, consisting of abundant elements, good thermal stability, and tunable electrochemical properties. [12] Benchmark PCEs of DSSCs have been achieved by the employment of porphyrin dyes such as GY50 (η = 12.8%), [13] SM315 (η = 13%), [14] SGT-021 (η = 12.1%), [15] and SGT-137/ SGT-021 tandem cell (η = 14.6%), in combination with cobalt electrolytes. [16] The superior performances of these dyes can be attributed to their particular donor-π-acceptor (D-π-A) structures for enhancing electron injection, compatibility with Porphyrins are an important category of dyes for efficient dye-sensitized solar cells (DSSCs). However, the efficiency improvement of DSSCs lags behind those of organic and perovskite solar cells owing to deficiencies in new design strategies of dye molecular structures. Recently, double fence porphyrins with superior photovoltaic performance were reported, in which eight alkoxyl chains were introduced to wrap the porphyrin core and retard the approach of the electrolyte to the surface of TiO 2 . On the basis of the design strategy of double fence porphyrins, novel porphyrins bJS8, YS2, YS3, YS7, and MC1 featuring dual functional indacenodithiophene group are synthesized and their photovoltaic p...
