Tetrabenzotriazacorrole and its derivatives as undoped hole transporting materials for perovskite solar cells: Synthesis, device fabrication, and device performance

Phthalocyanines, porphyrins and other porphyrinoids as components of perovskite solar cells

“…Stability tests revealed that TBC-1 conferred greater stability to PSCs than TBC-2 , H 2 -Pc-1 and spiro-OMeTAD, retaining 84% of the initial PCE after 30 days storage in a nitrogen glove box. 131 Lu and Zhang studied tetra(4- tert -butyl phenoxy)-tetrabenzocorrolazine phosphorous POTBC(β-OPB) 4 (Fig. 25b and Table 9) as dopant-free HTM in 3D n–i–p PSCs, comparing it with its precursor H 2 Pc(β-OPB) 4 and undoped spiro-OMeTAD.…”

Novel phosphorus(v) tetrabenzotriazacorroles: synthesis, characterization, optical, electrochemical, and femtosecond nonlinear optical studies

“…Despite the straightforward synthesis of TBCs and their interesting optical and electrochemical properties, they have been seldom explored for optoelectronic applications. 26–29…”

“…Despite the straightforward synthesis of TBCs and their interesting optical and electrochemical properties, they have been seldom explored for optoelectronic applications. [26][27][28][29] TBCs are potential NLO molecules with superior absorption properties compared to Pcs. Further, Pcs possess good thirdorder NLO properties compared to their second-order NLO properties because they possess a center of symmetry, and consequently the absence of a permanent dipole moment, which is important to demonstrate good second-order hyperpolarizability.…”

Investigation of mechanical properties of Ruddlesden-Popper 2D,2D-3D and 3D perovskites using an experimental and first principles approach

“…The XRD pattern for the 25P sample (2D-3D mixed perovskites) shows a dominating peak at around 15 o and around 29 o . These peaks can be either for the 3D [(110) and(220) planes respectively] or for 2D [(111) and(222) planes respectively] phases or for both quasi-2D and 3D peaks because the peaks are so close that it is difficult to differentiate between them[14,38].…”
