摘要：

Polycrystalline Si thin-film (poly-Si) solar cells need effective light-trapping to compensate for the moderate absorption. Recent developments in the poly-Si cell technology focus on film fabrication by e-beam evaporation due to its manufacturing benefits, such as a very high deposition rate above 15 nm/s and inline compatible process. However, evaporated poly-Si cells exhibit limited compatibility with textured glass. In this Letter, the coupling of the light in the absorber layer is enhanced by introducing a rough interface at the back of the solar cells. This increases the conversion efficiency from 6% to 7.1% for, respectively, planar and back textured interface with current density of 26.6 mA/cm(2) for only 3.6 mu m absorber thickness.
