| Popis: | High-efficient operation of a large-area thin film polycrystalline Si solar cell with a novel structure based on a silicon on insulator (SOI) structure prepared by zone-melting recrystallization (ZMR) is reported. The (100) crystal orientation area over 90% has successfully been obtained by controlling the ZMR conditions, which allowed to form a uniform random pyramidal structure at the cell surface. The effect of hydrogen passivation has also been investigated for further improvement of the cell characteristics. By employing a light trapping structure (textured surface) and hydrogen passivation, an efficiency of 14.22% was obtained for a practical 100 cm 2 size. |
