摘要
The past decade has witnessed rapid development in the syntheses and applications of porphyrin dyes, as the photosensitizer is crucial to determine the power conversion efficiency(PCE) of dye-sensitized solar cells(DSSCs) ~([1]).However, porphyrin dyes show typical absorbing defects in the regions of 350–410 nm and 500–600 nm ~([2]).To address the challenge, D–A–π–A indoline dye WS-5 was chosen as co-sensitizer for novel porphyrin dye FW-1 due to its complementary absorption spectra.As a result, compared to the single sensitizer FW-1, FW-1 + WS-5 shows a breakthrough of PCE from 6.53% and 7.05% to 10.22% and 10.42% based on I~-/I_3~- and Co(Ⅱ/Ⅲ) electrolyte, respectively, and additionally 10.80% under 0.79 sun irradiation with the latter electrolyte.To the best of our knowledge, this is the first time that PCEs are reported exceeding 10% for a porphyrin dye based on different redox shuttles, hence FW-1 + WS-5 offers a new avenue for basic understanding and also the practical development of DSSCs.
