      abstract     = {The development of a robust quasi-ohmic contact with
                      minimal resistance, good stability and cost-effectiveness is
                      crucial for perovskite solar cells. We introduce a generic
                      approach featuring a Lewis-acid layer sandwiched between
                      dopant-free semicrystalline polymer and metal electrode in
                      perovskite solar cells, resulting in an ideal quasi-ohmic
                      contact even at elevated temperature up to 85 °C. The
                      solubility of Lewis acid in alcohol facilitates
                      nondestructive solution processing on top of polymer, which
                      boosts hole injection from polymer into metal by two orders
                      of magnitude. By integrating the polymer-acid-metal
                      structure into solar cells, devices exhibit remarkable
                      resilience, retaining $96\%$ ± $3\%,$ $96\%$ ± $2\%$ and
                      $75\%$ ± $7\%$ of their initial efficiencies after
                      continuous operation in nitrogen at 35 °C for 2212 h,
                      55 °C for 1650 h and 85 °C for 937 h,
                      respectively. Leveraging the Arrhenius relation, we project
                      an impressive T80 lifetime of 26,126 h at 30 °C.},
