A Textured Sio2 Antireflection Layer for Efficient Organic Solar Cells
Surface topography(2014)
摘要
The effects of a textured SiO2 antireflective layer with regard to the improved performance of an organic photovoltaic device are explored. The surface root mean square roughness of the textured SiO2 layer increases when 3 nm Au nanoparticles are deposited on it after texture patterning by a reactive ion etching process. The optical transmittance of the textured SiO2 layer is increased, thereby enhancing the short-circuit current density. The power conversion efficiency of an organic solar cell with a textured SiO2 layer is improved from 2.02 +/- 0.02% to 2.13 +/- 0.03%.
