Abstract

Air-stable doping of the n-type fullerene layer in an n-i-p planar heterojunction perovskite device is capable of enhancing device efficiency and improving device stability. Employing a (HC(NH<sub>2</sub> )<sub>2</sub> )<sub>0.83</sub> Cs<sub>0.17</sub> Pb(I<sub>0.6</sub> Br<sub>0.4</sub> )<sub>3</sub> perovskite as the photoactive layer, glass-glass laminated devices are reported, which sustain 80% of their "post burn-in" efficiency over 3400 h under full sun illumination in ambient conditions.
