We introduce thiazolo[5,4-d]thiazole (TT)-based derivatives featuring carbazole, phenothiazine, or triphenylamine donor units as hole-selective materials to enhance the performance of wide-bandgap perovskite solar cells (PSCs). The optoelectronic properties underwent thorough evaluation and were substantially fine-tuned through deliberate molecular design. Time-of-flight hole mobility TTs ranged from 4.33 × 10–5 1.63 10–3 cm2 V–1 s–1 (at an electric field 1.6 105 V cm–1). Their ionization potentials −4.93 −5.59 eV. Using density functional theory (DFT) calculations, it has been demonstrated that S0 → S1 transitions in with carbazolyl ditert-butyl-phenothiazinyl substituents are characterized by local excitation (LE). Mixed intramolecular charge transfer (ICT) LE occurred for compounds containing ditert-butyl carbazolyl-, dimethoxy alkoxy-substituted triphenylamino moieties. selected TT used preparation layers (HSL) PSC structure glass/ITO/HSLs/Cs0.18FA0.82Pb(I0.8Br0.2)3/PEAI/PC61BM/BCP/Ag.
