Title: Comment on “Light-induced lattice expansion leads to high-efficiency perovskite solar cells”

Abstract

Tsai et al. report a uniform light-induced lattice expansion of metal halide perovskite films under 1-sun illumination and claim to exclude heat-induced lattice expansion. In this paper, we show that by controlling the temperature of the perovskite film under both dark and illuminated conditions, the mechanism for lattice expansion is in fact fully consistent with heat-induced thermal expansion during illumination.
