In this study, we implement a laser patterning process on organic-inorganic hybrid perovskite (OIHP) film and perform systematical investigation on the effects of aperture ratios. Through careful aperture ratio control and by using indium tin oxide (ITO) transparent electrode, we can fabricate neutral-colored semitransparent OIHP solar cells. Furthermore, we show that a LiF interlayer between OIHP and C60 electron transport layer (ETL) plays a bifunctional role of interface passivation and current flow rectification. Consequently, we demonstrate a high efficiency of 12.83 % power conversion efficiency (PCE) from a 2.00 cm2 and 9.30 % PCE from 36.00 cm2 area, with 21.74 % average visible transmittance (AVT). In addition, the neutral-colored semitransparent solar cell retains 89.02 % of its initial efficiency after 1,000 hours in dry-air storage without encapsulation.
