Marıne Calcıum Hydroxyapatıte as embryonıc materıal for excellent performance of perovskıte solar cell

Abstract

Marine calcium hydroxyapatite (HAp) extracted from fish bone has been perceived to be good as it carries good bioactivity and biocompatibility. In fact, the production of HAp from synthetic process involves many chemicals and complicated procedures which affect the stability. Extraction process of Hap from Selayang fish bone started with boiling fish bones to eliminate adherent fish meats, drying process and grinding process to obtain the powder. The extracted calcium was further used in syhthesis of calcium titanate perovskite (CaTiO3) for solar cell application. CaTiO3 has been known as a material with high efficiency and smaller band gap which fulfill the requirements for fabrication of the solar cell. The perovskite were synthesized in various ratios to observe the stability and coequal character with the standard perovskite. The novelty of this study lies between the method of extraction of HAp and the fabrication of perovskite where the calcium is substituted with HAp. The obtained HAp and CaTiO3 were characterized by using TGA, XRD and FTIR. The analytical results shows that HAp were formed after the calcinations process at 900°C and crystalinity of CaTiO3 was found at XRD peaks 47.8°, 48.2° and 68.5°. Highest efficiency was measured at sample H1T1 perovskite with 5.3%.
