We report an efficient hybrid Si microwire (radial junction) and planar solar cell with a maximum efficiency of 11.0% under AM 1.5G illumination. The maximum efficiency of the hybrid cell is improved from 7.2% to 11.0% by passivating the top surface and p-n junction with thin a-SiN:H and intrinsic poly-Si films, respectively, and is higher than that of planar cells of the identical layers due to increased light absorption and improved charge-carrier collections in both wires and planar components.
我们报告了一种高效的混合硅微线（径向结）和平面太阳能电池，在 AM 1.5G 光照下的最大效率为 11.0%。通过分别用薄的 a-SiN:H 和本征多晶硅薄膜钝化顶部表面和 p-n 结，使混合电池的最大效率从 7.2%提高到 11.0%，并且由于在微线和平面组件中增加了光吸收和改善了载流子收集，因此高于具有相同层的平面电池的效率。
