通过纳米压印光刻在玻璃板的表面上形成纳米尺度的聚合物图案，目的是减少光在表面处的反射。由于这种聚合物纳米图案小于光的波长，因此表面附近的有效折射率逐渐变化，并减少反射量。这种纳米图案形成在玻璃板的一侧或两侧，将用作太阳能电池器件的保护层。结果，与具有裸玻璃板的太阳能电池相比，具有双面图案化玻璃板作为保护层的太阳能电池在总转换效率上显示出高达2.5%的增加（5.14-5.27%）。(C)2009爱思唯尔有限公司版权所有。
A nanometer scale polymer pattern was formed on the surface of a glass plate by nano-imprint lithography with the aim of reducing the reflection of light at the surface. Since this polymeric nano-pattern is smaller than the wavelength of light, the effective refractive index near the surface changes gradually, and reduces the amount of reflection. Such a nano-pattern was formed on one or both sides of a glass plate, which will be used as the protective layer for solar cell devices. As a result, a solar cell with a both-side patterned glass plate as a protective layer showed up to 2.5% increase (5.14-5.27%) in total conversion efficiency, compared to a solar cell with a bare glass plate.
