Clarifying the structural basis and microscopic mechanism lying behind electronic properties of mol. semiconductors is of paramount importance in further material design to enhance the performance of perovskite solar cells. In this paper, three conjugated quasilinear segments of 9,9-dimethyl-9H-fluorene, 9,9-dimethyl-2,7-diphenyl-9H-fluorene, and 2,6-diphenyldithieno[3,2-b:2′,3′-d]thiophene are end-capped with two bis(4-methoxyphenyl)amino groups for structurally simple mol. semiconductors Z1, Z2, and Z3, which crystallize in the monoclinic P21/n, triclinic P1̅, and monoclinic C2/c space groups, resp. The modes and energies of intermol. noncovalent interactions in various closely packed dimers extracted from single crystals are computed based on the quantum theory of atoms in mols. and energy decomposition anal. Transfer integrals, reorganization energies, and center-of-mass distances in these dimers as well as band structures of single crystals are also calculated to define the theor. limit of hole transport and microscopic transport pictures. Joint X-ray diffraction and space-charge-limiting current measurements on solution-deposited films suggest the dominant role of crystallinity in thin-film hole mobility. Photoelectron spectroscopy and photoluminescence measurements show that an enhanced interfacial interaction between the perovskite and Z3 could attenuate the adverse impact of reducing the energetic driving force of hole extraction Our comparative studies show that the mol. semiconductor Z3 with a properly aligned HOMO energy level and a high thin-film mobility can be employed for efficient perovskite solar cells, achieving a good power conversion efficiency of 20.84%, which is even higher than that of 20.42% for the spiro-OMeTAD control. In the experiment, the researchers used many compounds, for example, Bis(4-methoxyphenyl)amine(cas: 101-70-2Application In Synthesis of Bis(4-methoxyphenyl)amine)
