MA₂CuCl₄ Perovskit Malzemenin Sentezlenmesi, Yapısal ve Optik Karakterizasyonu

Abstract

Bu çalışmada, kurşun içermeyen ve çevre dostu bir perovskit malzeme olan MA₂CuCl₄’ün sentezi gerçekleştirilmiş ve optoelektronik özellikleri incelenmiştir. MACl ve susuz CuCl₂’nin etanol içinde çözdürülmesi ile sarı renkte MA₂CuCl₄ kristalleri elde edilmiştir. Elde edilen malzemenin X-ışını kırınımı (XRD) ölçümleriyle yapısal özellikleri ortaya konmuştur. Scherrer denklemi yardımıyla kristal boyutu 65 nm olarak hesaplanmıştır. Toz numunenin EDS analizi sonucunda Cl/Cu oranı 3.6 bulunmuştur. Toz numenin ve FTO/TiO2 üzerine biriktirilmiş ince filmin Tauc eğrilerinden optik bant aralığı değerleri sırasıyla 2.38 eV ve 2.67 eV olarak belirlenmiştir.

Synthesis, Structural and Optical Characterization of MA₂CuCl₄ Perovskite Material

Abstract

In this study, the synthesis of MA₂CuCl₄, a lead-free and environmentally friendly perovskite material, was carried out and its optoelectronic properties were examined. Yellow MA₂CuCl₄ crystals were obtained by dissolving MACl and anhydrous CuCl₂ in ethanol. The structural properties of the synthesized material were revealed through X-ray diffraction (XRD) measurements, and the crystallite size was calculated as 65 nm using the Scherrer equation. Energy-dispersive X-ray spectroscopy (EDS) analysis of the powder sample yielded a Cl/Cu ratio of 3.6. The optical bandgap values determined from the Tauc plots of the powder sample and the thin film deposited on FTO/TiO₂ were 2.38 eV and 2.67 eV, respectively.
