Abstract

We report the development of instrumentation and methodology for fabricating large area semi-transparent organo-lead-halide perovskite films. In our method, the growth of perovskite films relies on the control of CH3NH3I flow and vapor pressure inside a vacuum chamber. Solar cell devices based on the prepared semi-transparent perovskite films as thin as ∼135 nm achieved an efficiency of 9.9% and a high open circuit voltage of 1.09 V.

Highlights

  • Fabrication of semi-transparent perovskite films with centimeter-scale superior uniformity by the hybrid deposition method† Cite this: Energy Environ

  • We report the development of instrumentation and methodology for fabricating large area semi-transparent organo-lead-halide perovskite films

  • It has been demonstrated that organo-lead-halide perovskite (OHP) based solar cells can achieve solar energy-to-electricity power conversion efficiency (PCE) as high as 16.2% and are compatible with protocols for low-cost solar cell fabrication.[1,2,3,4,5,6]
