文摘

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)_0.83Cs_0.17Pb(I_0.6Br_0.4)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.
