Although Me-4PACz improves the electronic properties (for example, compared to 2PACz and poly(triaryl amine)), the suboptimal formation of perovskite films on planar bottom cells/Me-4PACz often leads to macroscopic holes (Fig.2a). However, when the perovskite is spin-coated onto nanotextured si...
To address this, dipropyl sulfide (DPS) was incorporated into a solution of Me-4PACz. This approach not only enhances the wettability of Me-4PACz, facilitating the growth of larger perovskite grains but also enables Me-4PACz to form a homogeneous passivation layer with strong coverage. This ...
By contrast, the device with the adjusted HTL Me-4PACz has substantially degraded electronically (from JV scan) together with a loss in PL intensity (although on its own not sufficient to explain the drop in VOC, Supplementary Figs. 77 and 78), suggesting the interface is to blame for ...
In February, an international research group led by Yi fabricated an inverted perovskite solar cell by placing p-type antimony-doped tin oxides (ATOx) combined withmethyl-substituted carbazole(Me-4PACz)as an interlayer between the perovskite absorber and the hole-transporting layer (HTL). Th...
Furthermore, the NiO/Me-4PACz-based PeSC maintains 83% of their initial efficiency after 140 days in air. This result shows that our low temperature solution processed NiO/Me 4PACz can be a promising candidate as HTLs even in terms of stability. 展开 ...

Perovskite-based tandem solar cells have attracted increasing interest because of its great potential to surpass the Shockley–Queisser limit set for
33 reported monolithic perovskite/CIGS tandem solar cells with a certified PCE of 24.2% utilizing a large bandgap perovskite (1.68 eV) containing a PEAI additive, Me-4PACz monolayer as the HTM, and a LiF interlayer. This work demonstrates the high potential of perovskite/CIGS tandem solar ...
20 Following the 10 nm ITO recombination junction (deposited by DC sputtering) and the Me-4PACz hole transport layer, the perovskite solution with a composition Cs0.04FA0.80MA0.16Pb(I0.83Br0.17)3 was deposited by spin coating, yielding an absorber with a band gap of 1.67 eV, as measured ...
