Abstract Perovskite solar cells (PSCs) have rapidly developed and achieved power conversion efficiencies of over 20% with diverse technical routes. Particularly, planar‐structured PSCs can be fabricated low‐temperature (≤150 °C) solution‐based processes, which is energy efficient compatible flexible substrates. Here, the efficiency stability planar are enhanced by improving interface contact between SnO 2 electron‐transport layer (ETL) perovskite layer. A biological polymer (heparin...
