Abstract

Anorganik perovskite CsPbBr3 menjadi kandidat yang menjanjikan karena menunjukkan stabilitas thermal yang baik, terlebih untuk aplikasi sel surya. Penelitian ini bertujuan untuk menganalisis pengaruh temperatur annealing terhadap stabilitas struktur kristal dan luminesensi anorganik perovskite CsPbBr3, dengan variasi temperatur 90°C, 100°C, 110°C, 120°C, dan 130°C. Metode sintesis yang digunakan yaitu Ligan Assisted Reprecipitation (LARP). Sampel di karakterisasi dengan XRD untuk menganalisis stabilitas struktur kristal, selanjutnya di uji dengan TEM untuk menganalisis bentuk dan ukuran partikel. UV�Vis dan PL intensity untuk menganalisis stabilitas luminesensi.Hasil menunjukkan terbentuk anorganik perovskite CsPbBr3 dengan ukuran rata-rata partikel 35 nm yang berbentuk nanoplatelets. Seiring kenaikan temperatur hingga temperatur 130⁰C struktur kristal tetap stabil dengan struktur kubik,sedangkan luminesensi terjadi sedikit pergeseran ke blue shift area seiring kenaikan temperatur. Setelah dilakukan pengujian I-V pada sampel dengan ukuran 2 x 1 cm didapatkan nilai efisiensi sebesar 0,463 %, hal ini menunjukan material ini berpotensi untuk aplikasi sel surya

Inorganic perovskite CsPbBr3 nanocrystal is a promising
candidate, especially for solar cell applications. This study aims to
analyze the effect of annealing temperature on the stability of the
crystal structure and luminescence of inorganic CsPbBr3
perovskite , using temperature variations of 90°C, 100°C, 110°C,
120°C, and 130°C. The synthesis method used is Ligand Assisted
Reprecipitation (LARP). The samples were characterized by XRD
to analysis the crystal structure stability, TEM to determine the
morphology and particle size. UV-Vis and PL intensity tests to
analysis the luminescence stability of the CsPbBr3 inorganic
perovskite. The results showed the formation of inorganic CsPbBr3
perovskite with an average particle size of 35 nm in the form of
nanoplatelets. With an increase up to 130°C the crystal structure
remains stable with a cubic structure. Furthermore, for
luminescence there is a slight shift to the blue area (blue shift) as
the temperature increases. After the I-V test was carried out with
size 2 x 1 cm, an efficiency value of 0,463 %, this shows that this
material has the potential for solar cell applications.
