Constructing two-dimensional (2D) perovskite atop of 3D with energy landscape management is still a challenge in photovoltaics. Here, we report strategy through designing series π-conjugated organic cations to construct stable 2D perovskites and realize delicate level tunability at 2D/3D heterojunctions. As result, the hole transfer barriers can be reduced both heterojunctions within structures, preferable work function shift reduces charge accumulation interface. Leveraging these insights also benefitted from superior interface contact between conjugated poly(triarylamine) (PTAA) transporting layer, solar cell power conversion efficiency 24.6% has been achieved, which highest among PTAA-based n-i-p devices best our knowledge. The exhibit greatly enhanced stability reproducibility. This approach generic several materials, offering opportunities high without using unstable Spiro-OMeTAD.

Abstract With the rapid rise in device performance of perovskite solar cells (PSCs), overcoming instabilities under outdoor operating conditions has become most crucial obstacle toward their commercialization. Among stressors such as light, heat, voltage bias, and moisture, latter is arguably critical, it can decompose metal‐halide (MHP) photoactive absorbers instantly through its hygroscopic components (organic cations metal halides). In addition, charge transport layers (CTLs) commonly employed PSCs also degrade presence water. Furthermore, photovoltaic module fabrication encompasses several steps, laser processing, subcell interconnection, encapsulation, during which are exposed to ambient atmosphere. Therefore, a first step long‐term stable photovoltaics, vital engineer materials maximizing moisture resilience, be accomplished by passivating bulk MHP film, introducing passivation interlayers at top contact, exploiting hydrophobic CTLs, encapsulating finished devices with barrier layers, without jeopardizing performance. Here, existing strategies for enhancing stability reviewed pathways moisture‐resilient commercial formulated.
