| 摘要 |
The present invention relates to a thin film solar cell. The thin film solar cell comprises a substrate, a transparent conductive layer, a first semiconductor layer, a reflection layer, a reflection enhancing layer, a second semiconductor layer and an electrode layer. The transparent conductive layer is formed on the substrate. The first semiconductor layer is formed on the transparent conductive layer. The reflection layer is formed on the first semiconductor layer, and it is highly refraction and has a plurality of light-transmissive parts. The reflection enhancing layer is formed on the reflection layer, and it has at least a stacking layer including a low refraction index layer and a high refraction index layer. The second semiconductor layer is formed on the reflection enhancing layer. The electrode layer is formed on the second semiconductor layer. The light-transmissive parts are extended to the reflection enhancing layer.
