Abstract

Glucose fuel cell (GFC) hadir sebagai inovasi teknologi yang mampu menghasilkan listrik dengan mengonversi hidrogen melalui proses oksidasi glukosa menggunakan material semikonduktor yang berperan sebagai katalis. Perovskite thin film CsPbBr3 memiliki karakteristik photoelectrochemical yang unggul sebagai fotoanoda ketika dikombinasikan dengan FTO dan TiO2, tetapi memiliki stabilitas performa dan ketahananan yang rendah dalam sistem GFC. Oleh karena itu, penelitian ini bertujuan untuk menganalisis karakteristik morfologi thin film CsPbBr3 berbasis pelarut N-Methyl-2-pyrrolidone (NMP) dan matriks polycaprolactone (PCL) yang telah melalui heat treatment dengan variasi temperatur dan pengaruhnya terhadap stabilitas performa perovskite thin film CsPbBr3 dalam sistem glucose fuel cell. Pada penelitian ini dilakukan sintesis CsPbBr3 menggunakan metode Ligan-Assisted Reprecipitation Process (LARP) yang selanjutnya diberi perlakuan heat treatment dengan variasi tanpa perlakuan, heat treatment 90℃, dan heat treatment 110℃. Kemudian, dilakukan penambahan larutan NMP/PCL pada CsPbBr3 sebagai matriks dengan variasi rasio NMP:PCL yaitu 1:10, 1:5, dan 3:4. Setelah itu, fabrikasi fotoanoda dilakukan melalui metode dropcasting dengan urutan lapisan dari bawah, yaitu kaca FTO berukuran 2,5 cm x 2,5 cm, TiO2, dan CsPbBr3/NMP+PCL. CsPbBr3/NMP+PCL sesudah proses fabrikasi berupa thin film dilakukan beberapa pengujian, seperti SEM dan XRD untuk mengetahui pengaruh temperatur heat treatment terhadap morfologi serta struktur kristal yang terbentuk. Setelah itu, dalam rangka menganalisis stabilitas termal thin film setelah melalui heat treatment dilakukan pengujian TG/DTA. Pengujian PL dan UV-Vis juga dilakukan untuk mengetahui properti optik dari CsPbBr3/NMP+PCL. Kemudian, performa fotoanoda dalam GFC dianalisis melalui uji CV pada konsentrasi glukosa 0,1 M dan KOH 0,1 M dengan perbandingan volume 1:1 sehingga terjadi reaksi redoks yang efisien. Dengan demikian, penelitian ini akan menganalisis lebih jauh pengaruh penambahan NMP/PCL sebagai matriks fotoanoda dalam memperbaiki morfologi perovskite thin film CsPbBr3 dengan cara mengurangi pembentukan pinhole, memperbesar ukuran butir, dan memperluas film coverage. Selain itu, polaritas dan viskositas NMP yang rendah dapat meningkatkan stabilitas performa thin film CsPbBr3 dalam GFC.

Glucose fuel cell (GFC) is present as a technological innovation that is able to produce electricity by converting hydrogen through the glucose oxidation process using semiconductor materials that act as catalysts. Perovskite thin film CsPbBr3 has superior photoelectrochemical characteristics as a photoanode when combined with FTO and TiO2, but has low performance stability and durability in GFC systems. Therefore, this study aims to analyze the morphological characteristics of CsPbBr3 thin film based on N-Methyl-2-pyrrolidone (NMP) solvent and Polycaprolactone matrix (PCL) that have undergone heat treatment with temperature variations and their effect on the stability of CsPbBr3 thin film perovskite performance in glucose fuel cell system. In this study, CsPbBr3 synthesis was carried out through Ligan-Assisted Reprecipitation Process (LARP) which was then given heat treatment in conditions without treatment, heat treatment at 90°C, and heat treatment at 110°C. Then, NMP/PCL solution was added to CsPbBr3 as a matrix with variations in the NMP:PCL ratio, namely 1:10, 1:5, and 3:4. After that, photoanode fabrication is carried out through the dropcasting method with a layer sequence from the bottom, namely FTO glass measuring 2.5 cm x 2.5 cm, TiO2, and CsPbBr3/NMP+PCL. CsPbBr3/NMP+PCL after the fabrication process in the form of thin film is carried out several tests, such as SEM and XRD to determine the effect of heat treatment temperature on the morphology and crystal structure formed. After that, in order to analyze the thermal stability of thin film after heat treatment, TG/DTA testing was carried out. PL and UV-Vis tests are also carried out to determine the optical properties of CsPbBr3/NMP+PCL. Then, the performance of photoanodes in GFC was analyzed through CV test at glucose concentrations of 0.1 M and KOH 0.1 M with a volume ratio of 1:1 so that an efficient redox reaction occurred. Thus, this study will further analyze the effect of the addition of NMP/PCL as a photoanode matrix in improving the morphology of CsPbBr3 thin film perovskite by reducing pinhole formation, increasing grain size, and expanding film coverage. In addition, low polarity and viscosity of NMP can improve the performance stability of CsPbBr3 thin film in GFC.
