摘要: In this article, the light-trapping effect of textured back surface reflectors in thin-film Si solar cells is investigated. A unique substrate with a periodic dimple pattern has been developed by utilizing anodic oxidation Al as self-ordering process. n-i-p hydrogenated microcrystalline (μc-Si:H) fabricated on period 0.9 μm show an improved infrared response compared to those randomly substrates. high short circuit current density 24.3 mA/cm2 achieved 1-μm-thick μc-Si:H cell adopting patterned substrate.
