Abstract

Perovskit anorganik CsPbBr3 menunjukkan harapan karena stabilitas termal yang tinggi dan ketahanan di bawah suhu anil yang tinggi juga kondisi yang keras. Fabrikasi lapisan perovskit yang konsisten sangat penting untuk meningkatkan efisiensi sel surya tandem. Penelitian ini menyelidiki dampak dari perovskit CsPbBr3 dan suhu preparasinya terhadap efisiensi sel surya silikon polikristalin dalam struktur tandem dua terminal di bawah sinar matahari langsung. Perovskit disintesis menggunakan Ligand-Assisted Reprecipitation (LARP) dengan perlakuan suhu 25°C, 90°C, dan 110°C. Sampel-sampel CsPbBr3 dicampur dengan pelarut NMP/DMF dan diaplikasikan dengan cara drop coating untuk mendapatkan lapisan film yang lebih baik. Larutan CsPbBr3, tinta CsPbBr3/NMP/DMF, dan sel surya tandem Si/ CsPbBr3 dikarakterisasi dengan menggunakan XRD untuk mengetahui struktur kristal, SEM untuk mengetahui morfologi permukaan, UV-Vis untuk mengetahui spektrum absorpsi dan celah pita, PL untuk mengetahui analisis lapisan semikonduktor, dan pengujian kurva I-V untuk mengetahui ISC dan VOC untuk mengetahui efisiensi. Studi ini menunjukkan bahwa CsPbBr3 monoklinik mampu menahan anil pada suhu 110°C dan berhasil ditransformasikan menjadi film CsPbBr3 pada sel surya tandem, yang menghasilkan peningkatan sebesar 200,60% pada efisiensi konversi daya awal (PCE) dan peningkatan sebesar 32,61% setelah terpapar sinar matahari secara langsung dibandingkan dengan sel surya silikon polikristalin

Inorganic perovskite CsPbBr3 shows promise due to its high thermal stability and robustness under elevated annealing temperatures and harsh conditions. Consistent fabrication of perovskite layers is crucial for enhancing the efficiency of tandem solar cells. This study investigates the impact of CsPbBr3 perovskite and its preparation temperature on the efficiency of polycrystalline silicon solar cells in a two-terminal tandem structure under direct sunlight. The perovskite was synthesized using Ligand-Assisted Reprecipitation (LARP) with temperature treatments of 25°C, 90°C, and 110°C. The CsPbBr3 samples were mixed with NMP/DMF solvent and applied by drop coating for better film coverage. The CsPbBr3 solution, CsPbBr3/NMP/DMF ink, and Si/CsPbBr3 tandem solar cells were characterized using XRD for crystal structure, SEM for morphology, UV-Vis for absorption spectra and bandgap energy, PL for semiconductor layer analysis, and I-V curve testing to determine ISC and VOC for efficiency calculations. The study demonstrated that monoclinic CsPbBr3 was able to withstand annealing at 110°C and successfully transformed into a CsPbBr3 film on tandem solar cells, resulting in a 200.60% increase in initial power conversion efficiency (PCE) and a 32.61% increase after direct sunlight exposure compared to polycrystalline silicon solar cells.
