抄録

Organo lead halide perovskite absorbers were prepared by a two-step solution-processing method under ambient air conditions. Large cuboid crystalline grains that form a porous surface in junction with an organic hole conductor enable power conversion efficiency up to 15.3%, exhibiting minimal J–V hysteresis and stable performance against light intensity change. The cell without encapsulation showed sufficiently high stability under exposure to air.
