Abstract

Sel Surya berbasis Perovskit telah menjadi topik yang sedang banyak diteliti ilmuwan akhir akhir ini dikarenakan efisiensi yang cukup baik dan biaya pembuatan yang terjangkau. Sel surya perovskit adalah teknologi sel surya yang menggunakan material perovskit sebagai lapisan aktif untuk menghasilkan listrik dari energi matahari. Perovskit CH3NH3SnICl2 adalah salah satu variasi perovskit yang masih jarang diteliti. penelitian ini berfokus pada sintesis perovskit CH3NH3SnICl2 dengan pendekatan Reakayasa Pelarut dan mencari variasi paling optimal. Metode yang digunakan berupa rekayasa pelarut dimana saat sintesis perovskit CH3NH3SnICl2, perbandingan molar serta volume antara Dimethylsulfoxide (DMSO) akan divariasikan sehingga menghasilkan sampel dengan sifat sifat yang berbeda. Metode pelapisan larutan pada kaca substrat menggunakan metode Drop Casting dengan waktu pemanasan 30 menit. Selanjutnya lapisan film tipis Perovskit di karakterisasi dengan menggunakan Uji Kualitatif Perubahan Warna, Uji Scanning Electron Microscope (SEM), Uji UV – Vis dan Uji Resistivitas untuk mendapatkan informasi tentang morfologi, absorbansi dan celah energi pitanya, sifat semikonduktivitas dan kestabilan lapisan perovskit. Hasil penelitian menunjukkan bahwa variasi molar CH3NH3I dan SnICl2 secara signifikan mempengaruhi morfologi, resistivitas, dan kestabilan lapisan perovskit. Dalam segi degradasi warna lapisan, didapatkan bahwa sampel dengan komposisi molal dari CH3NH3I:SnCl2:DMSO 1:1:2 (sampel B) memiliki degradasi warna yang bertahan lama hingga 3 jam . Hasil pengukuran resistivitas dengan metode Four Point Probe pada tiga variasi sampel perovskit CH3NH3SnICl2 menunjukkan bahwa Sampel B memiliki nilai resistivitas yang lebih baik dengan nilai rata rata 8,9 × 10-4 Ωcm.

Perovskite-based solar cells have become a topic that is being researched a lot by scientists recently due to their good efficiency and affordable manufacturing costs. Perovskite solar cells are a solar cell technology that uses perovskite material as an active layer to produce electricity from solar energy. CH3NH3SnICl2 perovskite is a variation of perovskite that is still rarely studied. This research focuses on the synthesis of CH3NH3SnICl2 perovskite using a Solvent Reengineering approach and looking for the most optimal variation. The method used is solvent engineering where during the synthesis of CH3NH3SnICl2 perovskite, the molar and volume ratio between Dimethylsulfoxide (DMSO) will be varied to produce samples with different properties. The solution coating method on the glass substrate uses the Drop Casting method with a heating time of 30 minutes. Next, the Perovskite thin film layer was characterized using the Qualitative Color Change Test, Scanning Electron Microscope (SEM) Test, UV – Vis Test and Resistivity Test to obtain information about the morphology, absorbance and energy band gap, semiconductivity properties and stability of the perovskite layer. The results showed that molar variations of CH3NH3I and SnICl2 significantly influenced the morphology, resistivity and stability of the perovskite layer. In terms of coating color degradation, it was found that the sample with a molal composition of CH3NH3I:SnCl2:DMSO 1:1:2 (sample B) had color degradation that lasted up to 3 hours. The results of resistivity measurements using the Four Point Probe method on three variations of CH3NH3SnICl2 perovskite samples show that Sample B has a better resistivity value with an average value of 8,9 × 10-4 Ωcm.
