Abstract To the best of our knowledge, the solution-processed fabrication of perfectly (2 0 0)-oriented lead selenide (PbSe) films on various substrates, including glass, transparent conducting glass, and polyethylene terephthalate (PET) substrates, has been achieved for the first time. Herein, the effects of orientation parameters, including the acetate anion effect, crystallization temperature, and chemical composition, on solution-processed PbSe thin films were examined. Particularly, the presence of acetate anions in the precursor solution strongly affected the degree of orientation. X-ray diffraction analysis was employed, and X-ray diffraction pole-figure polar distance was scanned by rotating the sample about the incident beam direction. The experimental results confirmed the formation of perfectly (2 0 0)-oriented PbSe films.
