Achieving efficient, thick (&gt;700\u00a0nm), MA\u2010free WBG perovskites on textured silicon remains an unresolved challenge. Here, a coordination network coupled with \u03c0\u2013\u03c0 stacking work is designed to synchronize kinetics in MA\u2010free FACs\u2010based perovskite and promote conformal integration with textured silicon. A compact heterocyclic molecule simultaneously forms hydrogen\u2010bonds with FA cations and coordinates with the Pb\u2013I framework, while engaging in \u03c0\u2013\u03c0 stacking with underlying self\u2010assembled monolayers. This multi\u2010interaction synergy regulates nucleation and drives vertical crystal growth, yielding void\u2010free buried interfaces and columnar grains spanning the full film thickness. The reconstructed interface exhibits reduced trap density and favorable energy\u2010level alignment, enabling efficient hole extraction and suppressing electron back\u2010transport and mixed\u2010halide segregation. Consequently, the 1.68\u00a0eV MA\u2010free perovskite device achieves an efficiency of 24.04%. Monolithic P\/Si TSCs reach 33.04% efficiency, maintaining &gt;90% initial performance after 1600 h of maximum power point tracking. This work establishes a generalizable strategy to decoupling crystallization control from MA incorporation, enabling durable and high\u2010performance tandem photovoltaics.<\/jats:p>","DOI":"10.1002\/adma.75135","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T12:13:48Z","timestamp":1790252028000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhanced Interfacial Contact Enables Stable MA\u2010free Perovskite\u2013Silicon Tandem Photovoltaics"],"prefix":"10.1002","author":[{"given":"Jiyao","family":"Wei","sequence":"first","affiliation":[{"name":"State Key Laboratory of Silicon and Advanced Semiconductor Materials School of Materials Science and Engineering Zhejiang University  Hangzhou P.
