Three novel star shaped molecular architectures for D–π–D–π–D and (D–π)2–D–(π–D)2 anthracene based hole transporting materials are designed for organic-inorganic hybrid perovskite solar cells through Gaussian 09 computation.
Most high-performing organic-inorganic hybrid perovskite solar cells (PSC) are fabricated using expensive organic hole-transporting materials (HTM). The poor moisture- and thermal-stability of organic HTM is a significant factor contributing to...
Three spiro-acridine-fluorene based hole transporting materials (HTMs), namely CW3, CW4 and CW5, are employed in the fabrication of organic–inorganic hybrid perovskite solar cells.
Molecular hole-transporting materials containing a weak electron acceptor core can simultaneously improve the stability and photovoltaic performance of perovskite solar cells.
Three p-type small molecules (CL-1–3) based on tetraphenylethylene as the core and different π-conjugation diarylamines as linkers are synthesized. The bilayer HTL of the NiOx/CL-3-based cell exhibits the best power conversion efficiency of 20.15%.
