Recently, photovoltaics market is growing over the world, and polycrystalline silicon cell make up over 70% of all photovoltaic devices. The cell and the solar module are lead during manufacturing process. Therefore it is important to improve the strength reliability of the cell for highly reliable solar systems In this paper, the bending strength of photovoltaic cell was quantitatively measured at each manufacturing process, and the surface condition of the cell was observed by SEM. It was found that the strength of the cell was improved by reaction with metal-past.
