| Summary: | The world's energy needs are still dominated by the use of fossil fuels. But unfortunately, fossil fuels as an energy source have non-renewable properties so that fossil fuel resources are getting depleted. The potential for renewable energy in Indonesia reaches 400 GW and the largest potential, which is around 200 GW, comes from solar power. In perovskite solar cells (PSC), the material that is often used as an electron transport material (ETM) is TiO2. Indonesia is one of the countries that has abundant potential for TiO2. In this study, TiO2 synthesized from Bangka ilmenite will be used for electron transport material (ETM) perovskite solar cell (PSC) to determine its effect on the effectiveness of perovskite solar cell (PSC).
The research began with the synthesis of TiO2 from Bangka ilmenite using the caustic fusion method and then water leaching was carried out on the solid from the caustic fusion to remove excess NaOH. The next process is acid leaching with 8 M H2SO4 to obtain a precursor in the form of a TiSO4 solution. TiO2 powder synthesis was carried out using the sol-gel method on TiSO4 precursor. Perovskite Solar Cell fabrication begins by making a paste from TiO2 powder and mixed with terpineol and tritone as binder. TiO2 paste is used as electron transport material in Perovskite Solar Cells. The variables in this experiment were the type of TiO2 powder used and the amount of addition of colloid TiO2. The performance of the synthesized TiO2 PSC then compared with TiO2 P25 and TiO2 Anatase Merck's PSC.
Based on the research conducted, it shows that in Bangka ilmenite there is impurity in the form of Fe2O3 by 36.38% and has TiO2 content of 50.6%. TiO2 synthesis from Bangka ilmenite has crystals with an anatase phase with a band gap energy of 3.21 eV and spherical morphology with an average crytal size of 21,48 nm and particle size 0,16 ?m. PSC using synthetic TiO2 as electron transport material has efficiency about 0.29%. That is higher than the conversion efficiency of TiO2 Anatase Merck. In addition, this study also shows that the addition of colloidal TiO2 can increase the conversion efficiency of TiO2 P25 and TiO2 Anatase Merck. |
