Abstract

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(NH2 )2 )0.83 Cs0.17 Pb(I0.6 Br0.4 )3 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.
