Abstract The development of stretchable organic solar cells (s‐OSCs) demands concurrent breakthroughs in mechanical compliance and electronic properties, the challenge is rooted intrinsic mismatch between semiconductors metal electrodes. Here, this study proposes dual‐phase interface engineering strategies to reconcile these conflicting requirements through molecularly interlocked conductive elastomers. Dynamic stress dissipation dynamic bond plasticity achieved by embedding a 3D interpenetrating conducting elastomer network within electron transport layer (ETL). strategy creates gradient modulus interfaces Ag coordination‐enabled nanocomposite bonding, suppressing crack propagation velocities reduces interfacial phenomenon. Eventually, PCE 19.58% on small‐area flexible devices, which one highest PCEs for (f‐OSCs) date. Notably, devices retain over 10% under 100% tensile strain, surpassing previous photovoltaic devices. To further validate potential large‐area module applications, 25 cm 2 ‐based modules are prepared with 16.74% 14.48%, respectively. work redefines material design rules deformable electronics establishing generic mechanically adaptive framework that synchronizes dynamics across molecular macroscopic scales.
