      abstract     = {A key direction toward managing extrinsic instabilities in
                      perovskite solar cells (PSCs) is encapsulation. Thus, a
                      suitable sealing layer is required for an efficient device
                      encapsulation, preventing moisture and oxygen ingression
                      into the perovskite layer. In this work, a solution-based,
                      low-cost, and commercially available bilayer structure of
                      poly(methyl methacrylate)/styrene-butadiene (PMMA/SB) is
                      investigated for PSCs encapsulation. Encapsulated devices
                      retained $80\%$ of the initial power conversion efficiency
                      (PCE) at 85 °C temperature and $85\%$ relative humidity
                      after 100 h, while reference devices without SB (only PMMA)
                      suffer from rapid and intense degradation after only 2 h,
                      under the same condition. In addition, encapsulated devices
                      retained $95\%$ of the initial PCE under −15 °C freezing
                      temperature after 6 h and retained $∼80\%$ of the initial
                      PCE after immersion in HCl $(37\%)$ for 90 min. Moreover,
                      applying an additional aluminum metal sheet on the PMMA/SB
                      protective bilayer leads to the improvement of device
                      stability up to 500 h under outdoor illumination, retaining
                      almost $90\%$ of the initial PCE. Considering the urge to
                      develop reliable, scalable, and simple encapsulation for
                      future large-area PSCs, this work establishes solution-based
                      bilayer encapsulation, which is applicable for flexible
                      solar modules as well as other optoelectronic devices such
                      as light-emitting devices and photodetectors.},
