Its optical and electrochemical properties were also investigated together with its use as sensitizer in dye-sensitized solar cells (DSSCs). The performance of TT260 was compared with a benchmark molecule TT1, bearing similar bulky tert-butyl groups at the periphery. The device, which is the first ever example of meso-substituted TBTAP-based DSSC, exhibits a modest maximum power conversion efficiency of 2.4±0.1 % under one-sun conditionsengjournal articlehttps://doi.org/10.1002/hlca.202000085restricted access615.31615:54Phthalocyaninestetrabenzotriazaporphyrinsdye-sensitized solar cellsphotosensitizersphotochemistryQuímica farmaceútica23 Química
