Diiodomethane (CH₂I₂) has been reported to improve the photonically cured perovskite solar cell (PSC) device performance by reducing pinholes. Here we show that even for pinhole-free methylammonium lead iodide (MAPbI₃) made by photonic curing, adding CH₂I₂ promotes significant performance improvement. We elucidate the mechanisms behind the observed improvement. In addition to current-density versus voltage measurements, we perform a wide variety of characterization to compare the crystallinity, grain structure, optical, chemical, and electrical properties of the photonically cured samples with and without CH₂I₂ in the MAPbI₃ layer to those of thermally annealed devices. Here, the addition of CH₂I₂ promotes grain growth in the vertical direction, increases the I/Pb ratio in the final film, and removes the I^- ionic diffusion and defect signature associated with iodine interstitials. As a result, we achieve a champion efficiency of 15.04% with MAPbI₃ conversion time of 20 ms, comparable to PSCs that have MAPbI₃ layer thermally annealed for 10 min. Understanding the mechanisms behind additive-induced improvements for non-thermal annealing processes is critical to enabling high-speed PSC manufacturing.
