A simple and efficient process for fabricating high efficiency polycrystalline silicon ribbon solar cells

The aim of this work is to clarify the potential of the low cost polycrystalline silicon String Ribbon for fabricating high efficiency solar cells with gettering and passivation techniques. The application of P and Al gettering as well as SiO₂ and H passivation schemes enhanced the material quality and boosted the efficiency of the solar cells. A cell efficiency above 15% has been achieved using a simple fabrication process.
