Solvents were purchased from Sigma-Aldrich (highest purity and anhydrous); lead iodide (PbI2, 99.99% purity) and (2-(3,6-Dimethoxy-9H-carbazol-9-yl)ethyl)phosphonic acid (MeO-2PACz) were purchased from TCI; organic iodide salts (MAI, MACl, TMAI) were purchased from GreatCell Solar. (...
synthesized a new SAM with aligned energy levels and favorable dipole moments, which was based on MeO-2PACz, called ((2,7-dimethoxy-9H-carba-zol-9-yl) methyl) phosphonic acid (DC-PA)104. An alkyl ammonium salt, IAHA, was introduced into the DC-PA solution to form co-SAM. The HOMO...

"Our new strategy leads to record-performing flexible solar cells and represents a significant step toward the fabrication of flexible photovoltaics in the future," Tan said. "We also showed that mixing two SAMs (2PACz and MeO-2PACz) with different dipole moments can flexibly tune the energy l...

al. devised (monolayer MeO-2PACz-Cs0.05MA0.17 FA0.83Pb(I0.83Br0.17)3- BCP-C60) PSC on standard CIGS cell and described the advantage of simple monolayer HTL over expensive and complex deposited thick HTL and reported tandem PCE of 23.3 % [19]. Fan et. al. reported experimentally measured...
2PACz and MeO-2PACz was used to adjust the energy-level alignment between NiO and the wide-bandgap perovskite, as the molecular dipole moments of 2PACz and MeO-2PACz are notably different (2.0 D and 0.2 D, respectively). Using this strategy, a flexible all-perovskite tandem solar cell ...

(Fig.3g), indicating excellent bulk perovskite quality. Considering the MeO-2PACz/perovskite stacks, we observe a slight decrease in the QFLS, shifting to around 1.225 eV for both samples, due to the addition of the bottom interface. This similar behavior suggests that no additional ...
