Abstract

Indonesia has a large solar energy potential, presenting a sustainable alternative to fossil
fuels. However, challenges in mass implementation such as limited technology, costly
materials, and low efficiency of local solar cells must be addressed. Si/perovskite tandem solar
cell emerged as a solution for its affordability, simplified production, and power conversion
efficiency. Despite that, the material stability remains uncertain. Therefore, this study aims to
analyze the morphological and efficiency stability of Si/perovskite TSC using polycrystalline
solar cell based on CsPbBr3 post-treatment temperature under two conditions, full spectrum
solar simulator and direct sunlight. The mechanism of experiment was carried out by
synthesizing a CsPbBr3 solution using Ligand Assisted Reprecipitation (LARP) method. The
solution is treated with variations of without heating at 25 °C and with heat treatment at 90 and
110 °C before fabricated into CsPbBr3/NMP/DMF coating solution to assemble 2T TSC. The
SEM and XRD tested to analyze the morphology stability reveal that particle size distribution
increases with post-treatment temperatures, particles evolve from 2D to 3D shapes due to heat
and crystal phase CsPbBr3 generate byproducts CsPb2Br5 and Cs4PbBr6, with presence of
polycrystalline. The highest morphological stability is achieved at 110 °C under direct sunlight.
UV-vis and photoluminescence test analyzed the optical properties highlighting bandgap
energy with an absorption edge, spanning regions in light spectrum and device’s ability to emit
the electrons. I-V curve testing analyze the optimal efficiency stability attained at 110 °C under
direct sunlight, the PCE starts at 20%, peaks at 24%, and remains above 20% for 20 days.

Potensi energi surya Indonesia sangat besar, menawarkan alternatif terhadap bahan bakar
fosil. Namun, tantangan dalam implementasi massal seperti teknologi yang terbatas, bahan
berbiaya tinggi, dan efisiensi rendah sel surya lokal perlu diatasi. Sel surya tandem Si/perovskite
muncul sebagai solusi karena harga terjangkau, produksi yang sederhana, dan power conversion
efficiency. Meskipun demikian, stabilitas material masih belum dapat dipastikan. Menggunakan
polycrystalline solar cell Si/perovskite berdasarkan post-treatment temperature CsPbBr3 di
bawah dua kondisi, solar simulator dan sinar matahari langsung. Mekanisme eksperimen
dilakukan dengan mensintesis larutan CsPbBr3 menggunakan metode Ligand Assisted
Reprecipitation (LARP). Larutan ini diperlakukan dengan variasi tanpa pemanasan dan dengan
perlakuan panas pada 90 dan 110 °C sebelum difabrikasi menjadi larutan coating
CsPbBr3/NMP/DMF untuk membuat rangkaian TSC 2T. Pengujian SEM dan XRD untuk
menganalisis stabilitas morfologi menunjukkan bahwa distribusi ukuran partikel meningkat
dengan suhu perlakuan, partikel berubah dari bentuk 2D ke 3D karena panas dan fase kristal
CsPbBr3 bertransformasi menjadi CsPb2Br5 dan Cs4PbBr6, dengan struktur polycrystalline.
Stabilitas morfologi tertinggi dicapai pada 110 °C di bawah sinar matahari langsung. Pengujian
UV-Vis dan PL menganalisis sifat optik dengan menunjukan energi bandgap dengan absorption
edge, mencakup berbagai spektrum cahaya dan kemampuan rangkaian untuk mengemisikan
elektron. Pengujian I-V curve menganalisis stabilitas efisiensi optimal yang diperoleh pada
110°C di bawah sinar matahari langsung, di mana PCE dimulai pada 20%, memuncak pada
24%, dan tetap di atas 20% selama 20 hari.
