OPTICAL PROPERTIES OF BaTi0,99Sr0,01O3 SOLAR CELLS: A MOLECULAR MODELİNG STUDY

Nowadays, energy resources (oil, coal and natural gas) are limited, studies on turning to alternative or sustainable energies have increased in recent years. Among the sustainable energy sources, solar energy attracts the most attention. Researchers in many industries are engineering all kinds of better-performing materials, abourt solar cells The most important point in using solar energy is the efficient conversion of sunlight into electrical energy. I this study Sr doped BaTiO3 candidate has strong photorefractive sensitivity and large electrooptic coefficients, making it a suitable crystal for use as a semiconductor in photovoltaic systems. In this study, optical properties of BaTiO3 were calculated with Denstiy Functional Theory (DFT).
