Abstract

Penelitian mempelajari proses fabrikasi lapisan tipis Cadmium Sulfide Quantum Dots (CdS QDs) dengan Polyvynil Alcohol (PVA) tanpa proses penyaringan butir endapan sebagai penyusun modul sel surya tersensitisasi. Substrat yang digunakan yakni kaca Fluorine-doped Tin Oxide (FTO). Tahapan dalam melakukan penelitian ini meliputi fabrikasi menggunakan metode Chemical Bath Deposition (CBD), dan pengujian. Lapisan tipis CdS QDs difabrikasi dengan PVA sebagai agen pembatas. Pengujian yang dilakukan yakni spektrofotometri UV/Vis, XRD, dan karakteristik elektris. Berdasarkan hasil pengujian, diperoleh lapisan tipis CdS QDs berwarna kuning pucat mengindikasikan terdapatnya PVA dan lapisan tipis CdS berwarna kuning pekat menunjukkan lapisan kaya akan CdS murni. Besar pita energi (Eg) lapisan tipis CdS QDs yakni 4,08 eV dan lapisan tipis CdS yakni 2,37 eV. Nilai Fill Factor (FF) modul sel surya tersensitisasi CdS QDs yakni 0,193 dan modul sel surya lapisan tipis CdS yakni 0,314. Besar efisiensi (η) modul sel surya tersensitisasi CdS QDs yakni 0,004% dan modul lapisan tipis CdS yakni 0,030%. Terdapatnya PVA pada lapisan tipis CdS QDs mengakibatkan lapisan tipis seperti dalam fasa amorf dan memiliki sifat isolator. ====================================================================================================== The research studied the process of fabricating a thin layer of Cadmium Sulfide Quantum Dots (CdS QDs) using Polyvynil Alcohol (PVA) without going through the process of filtering sediment grains as a thin layer of sensitized solar cell modules. The substrate used is Fluorin-doped Tin Oxide (FTO). The stages in conducting this research include fabrication using Chemical Bath Deposition method, and testing. A thin layer of CdS QDs was fabricated using PVA as a capping agent. The testing includes UV/Vis spectrophotometry, XRD, and electrical characteristics. Based on the test results, it was obtained that a pale yellow CdS QDs thin layer indicated the presence of PVA and a dense yellow CdS thin layer indicated a pure CdS rich layer. The energy bandgap (Eg) of the CdS QDs thin layer is 4,08 eV and the CdS thin layer is 2,37 eV. Fill Factor (FF) value of CdS QDs sensitized solar cell module is 0,193 and CdS thin layer solar cell module is 0,314. Efficiency (η) of CdS QDs sensitized solar cell module is 0,004% and CdS thin layer module is 0,030%. The presence of PVA in the thin layer of CdS QDs resulted in the thin layer being in an amorphous like phase and having insulating properties.
