Our analysis of reflection spectra and X-ray diffraction profiles confirmed the formation of the leadhalide perovskite structures with this exposure process.This approach provides a promising pathway for environmentally friendly perovskite solar cells, eliminating the need for toxic polar organic solvents (for example, DMF, DMSO and so on) commonly employed in conventional perovskite solar cell fabrication.抄録：英語フィールド
