      abstract     = {Fully printed flexible perovskite solar cells (f-PSCs) show
                      great potential for the commercialization of perovskite
                      photovoltaics owing to their compatibility with
                      high-throughput roll-to-roll (R2R) production. However, the
                      challenge remains in the deficiency in controlling
                      interfacial recombination losses of the functional layer,
                      causing remarkable loss of power conversion efficiency (PCE)
                      in industrial production. Here, a fullerene-substituted
                      alkylphosphonic acid dipole layer is introduced between the
                      R2R-printed tin oxide electron transport layer and the
                      perovskite active layer to reduce the energetic barrier and
                      to suppress surface recombination at the buried interface.
                      The resulting f-PSCs exhibit a PCE of $17.0\%$ with
                      negligible hysteresis, retain $95\%$ of their initial PCE
                      over 3000 bending cycles and achieve a T95 lifetime of 1200
                      h under 1 sun and 65 °C in nitrogen atmosphere. Moreover,
                      the fully printed flexible perovskite solar mini-modules
                      (f-PSMs) with a 20.25 cm2 aperture area achieve a PCE of
                      $11.6\%.$ The encapsulated f-PSMs retain $90\%$ of their
                      initial PCE after 500 h damp-heat testing at 65 °C and
                      $85\%$ relative humidity (ISOS-D3). This work marks an
                      important progress toward the realization of efficient and
                      stable flexible perovskite photovoltaics for
                      commercialization.},
