Perovskite/organic tandem solar cells (POTSCs) are gaining attention due to their easy fabrication, potential surpass the S-Q limit, and superior flexibility. However, low power conversion efficiencies (PCEs) of wide bandgap (Eg) perovskite (PVSCs) have hindered development. This work presents a novel effective mixed-cation passivation strategy (CE) passivate various types traps in wide-Eg perovskite. The complementary effect 4-trifluoro phenethylammonium (CF3 -PEA+ , denoted as CA+ ) ethylenediammonium (EDA2+ EA2+ reduces both electron/hole defect densities non-radiative recombination rate, resulting record open-circuit voltage (Voc PVSCs (1.35 V) high fill factor (FF) 83.29%. These improvements lead PCE 24.47% when applied fabricated POTSCs, highest date. Furthermore, unencapsulated POTSCs exhibit excellent photo thermal stability, retaining over 90% initial after maximum point (MPP) tracking or exposure 60 °C for 500 h. findings imply that synergic surface passivators is promising achieve high-efficiency stable corresponding POTSCs.

Surface passivation has been developed as an effective strategy to reduce trap-state density and suppress non-radiation recombination process in perovskite solar cells. However, agents usually own poor conductivity hold negative impact on the charge carrier transport device. Here, we report a binary synergistical post-treatment method by blending 4-tert-butyl-benzylammonium iodide with phenylpropylammonium spin-coating surface form layer. The post-treated films show enhanced crystallinity improved molecular packing well better energy band alignment, benefiting for hole extraction transfer. Moreover, defects are further passivated compared unary passivation. Based strategy, record-certified quasi-steady power conversion efficiency of 26.0% cells is achieved. devices could maintain 81% initial after 450 h maximum point tracking.

Abstract Perovskite/silicon tandem solar cells hold great promise for realizing high power conversion efficiency at low cost. However, achieving scalable fabrication of wide-bandgap perovskite (~1.68 eV) in air, without the protective environment an inert atmosphere, remains challenging due to moisture-induced degradation films. Herein, this study reveals that extent moisture interference is significantly influenced by properties solvent. We further demonstrate n-Butanol (nBA), with its polarity and moderate volatilization rate, not only mitigates detrimental effects air during but also enhances uniformity This approach enables us achieve impressive 29.4% (certified 28.7%) double-sided textured perovskite/silicon featuring large-size pyramids (2–3 μm) 26.3% over aperture area 16 cm 2 . advance provides a route large-scale production cells, marking significant stride toward their commercial viability.
