      abstract     = {Commercialization of perovskite photovoltaics hinges on the
                      successful transition from laboratory-scale fabrication to
                      industrial-scale manufacturing. A key challenge in fully
                      printed perovskite solar cells with non-reflecting back
                      electrodes is the deposition of high-quality,
                      over-one-micron-thick perovskite layers to minimize
                      photocurrent losses from incomplete light absorption.
                      However, the formation of voids at the substrate/perovskite
                      interface impedes the fabrication of such layers. Here,
                      phase-field simulations reveal that the bottom voids
                      originate from trapped residual solvents, driven by
                      nanocrystal aggregation at the liquid–vapor interface
                      during drying. Guided by these insights, we introduce a
                      two-dimensional (2D) perovskite layer-assisted growth
                      strategy to promote heterogeneous nucleation at the
                      substrate, accelerating 3D perovskite crystallization and
                      preventing solvent entrapment. This strategy enables the
                      formation of highly crystalline, monolithic perovskite films
                      exceeding one micrometer in thickness. The resulting
                      void-free films maximize photocurrent extraction, achieving
                      power conversion efficiencies of $19.9\%$ on rigid
                      substrates and $17.5\%$ on flexible substrates in fully
                      printed perovskite solar cells with non-reflecting carbon
                      electrodes.},
