recommendations! Published in 2022 at "Applied Surface Science"

DOI: 10.1016/j.apsusc.2021.151301

Abstract: Abstract The hole transport layer (HTL) plays a key role in determining the performance of planar perovskite solar cells (PSCs). Poly[bis(4-phenyl)(2,4, 6-triMethylphenyl)aMine] (PTAA), a polymer with good stability, is one of the promising HTL candidates… read more here.

DOI: 10.1039/d5sc04440e

Abstract: The Li-TFSI/t-BP system is essential for doping the hole-transporting layer (HTL) to construct efficient perovskite solar cells (PSCs). However, the hygroscopicity and Li+ migration of Li-TFSI, as well as the corrosiveness and volatility of t-BP,… read more here.

DOI: 10.1364/prj.398529

Abstract: Modifying the surface of poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA) with toluene during the high-speed spin-coating process of dimethylformamide considerably improves the wettability and morphology of PTAA and results in improvement of the crystallinity and absorption of perovskite film.… read more here.
