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...
Me 4PACz modification on NiO results in an improved energy level alignment with perovskite and more hydrophobic NiO/Me 4PACz induces excellent perovskite layer with larger grain and high crystallinity. Furthermore, the NiO/Me-4PACz-based PeSC maintains 83% of their initial efficiency after 140 ...

The molecular hybrid of Me-4PACz with NA could substantially improve the interfacial characteristics. The resulting inverted perovskite solar cells demonstrated a record certified steady-state efficiency of 26.54%. Crucially, this strategy aligns seamlessly with large-scale manufacturing, achieving one of ...

(partly) textured silicon heterojunction (SHJ) bottom cell are ideal. An ultra-thin interfacial recombination layer (~ 5 nm) of indium tin oxide (ITO) or indium zinc oxide (IZO) containing a carbazole-based hole transporting self-assembled monolayer (Me-4PACz) is used for optimal 2-...
As a result, a uniform perovskite layer is deposited on top of Me‐4PACz through a very simple VD process, achieving 20.31% efficiency, which is not only close to the highest efficiency among Me‐4PACz‐based PSCs, but also improved long‐term stability of the device. It...

Afterward, based on previous research, they further designed a new type of SAM, [4-(3,6-dimethyl-9H-carbazol-9-yl)butyl] phosphonic acid (Me-4PACz), and fabricated perovskite/silicon tandem solar cells with a certified efficiency exceeding 29%21. Recently, Jen et al. synthesized a new ...
