Perovskite solar cells (PSCs) are promising alternatives toward clean energy because of their high-power
conversion efficiency (PCE) and low materials and processing cost. However, their poor stability under
operation still limits their practical applications. Here we design an innovative approach to control the
surface growth of a low dimensional perovskite layer on top of a bulk three-dimensional (3D) perovskite
film. This results in a structured perovskite interface where a distinct layered low dimensional perovskite
is engineered on top of the 3D film. Structural and optical properties of the stack are investigated and
solar cells are realized. When embodying the low dimensional perovskite layer, the photovoltaic cells
exhibit an enhanced PCE of 20.1% on average, when compared to pristine 3D perovskite. In addition,
superior stability is observed: the devices retain 85% of the initial PCE stressed under one sun illumination
for 800 hours at 50
