Abstract
Hidrogen menjadi alternatif baru sebagai sumber energi yang ramah lingkungan, namun, sekitar 95% produksinya masih bergantung pada bahan bakar fosil sehingga diperlukan produksi hidrogen yang lebih ramah lingkungan seperti metode photoelectrochemical (PEC). Kombinasi antara photoelectrochemical dengan pemanfaatan glucose fuel cell sangat berpotensi untuk dimanfaatkan sebagai penghasil listrik. Oleh karena itu penelitian ini bertujuan untuk menganalisis pengaruh perubahan morfologi CsPbBr3 karena heat treatment terhadap sifat optik fotoanoda dan terhadap performa produksi hidrogen dalam sistem glucose fuel cell. Mekanisme pada penelitian ini dilakukan dengan mensintesis larutan CsPbBr3 dengan metode Ligan Assisted Reprecipitation (LARP) kemudian dilanjutkan dengan fabrikasi fotoanoda FTO/C-TiO2/CsPbBr3 diberi perlakuan dengan variasi tanpa heating treatment dan dengan heating treatment pada temperatur 90℃ dan 110℃ serta konsentrasi larutan glucose 0 M; 0,1 M; dan 0,3 M. Penelitian dilakukan pengujian Photoluminescence dan UV-Visible pada larutan CsPbBr3 untuk mengetahui terjadinya transfer energi pada elektron dan sifat optik penyerapan cahaya pada larutan yang didapatkan wavelenght sesuai seiring dengan kenaikan temperatur yaitu pada sekitar 518-520 nm dan bandgap pada rentang 2,30-2,28 eV. Bandgap tersebut sesuai dengan hasil ukuran kristal pada pengujian XRD. Dimana semakin kecil ukuran kristal maka semakin besar bandgap yang dihasilkan. Pengujian Scanning Elektron Microscopy juga dilakukan untuk menganalisi morfologi pada fotoanoda FTO/C-TiO2/CsPbBr3. Dilakukan pengujian Cyclic Voltametry untuk mengetahui reaksi reduksi oksidasi serta diuji menggunakan Linear Sweep Voltametry untuk dilakukan perhitungan terbentuknya hidrogen pada proses glucose fuel cell. Performa produksi arus dan hidrogen dari CsPbBr3 dengan temperatur ruangan menunjukkan hasil yang paling optimal pada variasi temperatur ruangan pada konsentrasi 0.1 M yaitu sebesar 8.2411 mA/cm2.

Hydrogen has become a new alternative as an environmentally friendly energy source, but around 95% of its production still depends on fossil fuels, so more environmentally friendly hydrogen production is needed, such as the photoelectrochemical (PEC) method. The combination of photoelectrochemistry with the use of glucose fuel cells has the potential to be used as an electricity producer. Therefore, this study aims to analyze the effect of changes in the morphology of CsPbBr3 due to heat treatment on the optical properties of the photoanode and on the hydrogen production performance in the glucose fuel cell system. The mechanism in this research was carried out by synthesizing a CsPbBr3 solution using the Ligand Assisted Reprecipitation (LARP) method then followed by fabricating an FTO/C-TiO2/CsPbBr3 photoanode which was treated with variations without heating treatment and with heating treatment at temperatures of 90℃ and 110℃ and concentrations 0 M glucose solution; 0.1 million; and 0.3 M. The research carried out Photoluminescence and UV-visible testing in the CsPbBr3 environment to determine the occurrence of energy transfer in elektrons and the optical properties of light absorption in solutions obtained at appropriate wavelengths along with increasing temperature, namely at around 518-520 nm and bandgap at range 2.30-2.28 eV. The bandgap is by the crystal size results in XRD testing. Where the smaller the crystal size, the larger the bandgap produced. Scanning Elektron Microscopy testing was also carried out to analyze the morphology of the FTO/C-TiO2/CsPbBr3 photoanode. Cyclic Voltammetry testing was carried out to determine the oxidation-reduction reaction and tested using Linear Sweep Voltammetry to calculate hydrogen formation in the glucose fuel cell process. The current and hydrogen production performance of CsPbBr3 at room temperature shows the most optimal results at room temperature variations at a concentration of 0.1 M, namely 8.2411 mA/cm2.
