SOLAR CELL WITH OMNIDIRECTIONAL ANTI-REFLECTION STRUCTURE AND METHOD FOR FABRICATING THE SAME |
| 摘要 |
A solar cell with an omnidirectional anti-reflection structure comprises a solar cell substrate, a transparent electric-conduction layer formed on one surface of the solar cell substrate, a plurality of microspheres formed on the transparent electric-conduction layer, and a dielectric layer. The microspheres have a diameter of 0.1-100 μm. The dielectric layer is formed among the microspheres, and covers the surface of the transparent electric-conduction layer without the microspheres and has a thickness smaller than the diameter of the microspheres. Thus, the above-mentioned structure can enhance the absorption of the short-wavelength spectrum and increase the short-circuit current. Further, the structure with the microspheres is adaptable to the omnidirectional light absorption at various incident angles. |
