Dopant-free planar n-i-p perovskite solar cells with steady-state efficiencies exceeding 18%
In this Letter, we demonstrate a planar n–i–p perovskite solar cell design with a steady-state efficiency of up to 18.8% in the absence of any electronic dopants. In the device stack, solution-processed SnO2 is used as an electron-accepting n-type layer. The absorber layer is a perovskite with both...
