Continuously adjustable HOMO levels and high hole mobility are obtained by the structural tailoring of auxiliary TPA-donors.
Development of ideal small-molecule hole-transporting materials (HTMs) is one the most effective means to improve performance perovskite solar cells. Meanwhile, theoretical chemistry method an efficient pathway optimize molecular structure and probe structure–property relationship. To further find new HTMs, thia[5]helicene its counterpart perylothiophene are introduced into D−π–A-type scaffold MPA-BT-CA, results show that helicene-type HTMs (SM46 SM48) exhibit obvious advantages in...
Due to the attractive optoelectronic properties and extensive application in solar cells, design of new helicene-type molecular semiconductors is remarkable importance for development high-efficiency hole-transporting materials (HTMs). In this work, three helicene HTMs are constructed on basis conformation experimentally reported T5H-OMeDPA by replacing thia[5]helicene unit with a more curved π-linker dithia[6]helicene considering effects fluorine substitution. The electronic optical...
Based on the D–A–D scaffold, six benzothiadiazole-based HTMs are tailored by using phenoxazine, phenothiazine and carbazole as donors, their electronic, optical, hole-transporting interfacial properties evaluated theoretically.
Design of a new spiro-typed core structure is one the most important approaches for developing highly efficient hole-transporting materials (HTMs). In this work, strategies modifying with O/S heteroatoms and introducing helical π-linker are evaluated based on typical FDT molecule. Theoretical calculations show that all highest occupied molecular orbitals (HOMOs) lowest unoccupied (LUMOs) studied HTMs matched well energy band perovskite, HOMO levels display gradually negative-shifted trend...
Density functional theory (DFT) and time-dependent DFT (TDDFT) calculations have been carried out on the electronic structure optical properties of a set heterocycle-fused zinc porphyrazine (ZnPz) derivatives, aiming at screening efficient sensitizers for dye-sensitized solar cells (DSSCs). Our results show that absorption spectra designed dyes shift to longer wavelengths light harvesting efficiencies are much higher than isolated ZnPz. Moreover, larger contributions anchoring group lowest...
Abstract To reduce intrinsic defect density in perovskite films, various additives are often added into the precursor solution. In this paper, a novel solution, which isopropanol (IPA) was developed for preparation of normal planar solar cells (PSCs). A champion power conversion efficiency (PCE) 19.70 % achieved with approach. By adding IPA CH 3 NH PbI showed better crystallization and stability, indicating improved film quality. Because morphology crystal, PCE PSCs increased. addition,...
A series of small molecule HTMs with two-dimensional and three-dimensional cores is simulated the results show that exhibit superiorities in comparison cores.
Phenanthrothiadiazole (PT) and triphenylenobisthiadiazole (TBT) are proposed as the acceptor groups of D–A–D-type HTMs, compared with benzothiadiazole (BT) unit, three small molecule HTMs investigated theoretically.
We theoretically describe the effects of chemically modifying polypyridine ligands and design efficient Co-based redox mediators for dye-sensitized solar cells.
