  • Methods and structures for improving the structural integrity of solar cells
    Patent number: 9640676
    Abstract: A method for manufacturing solar cells is disclosed. The method includes forming an insulating material in a printable suspension along the at least one side edge of a solar cell, the insulating material in a printable suspension further adapted to form a protective film which reduces cracking near at least one side edge of the solar cell and improve structural integrity against mechanical stress. The protective film has an elastic modulus of at least 3 GPa, an elongation break point of at least 13 percent and a glass transition temperature of at least 250 degrees Celsius which provides additional structural support along the side edges, increasing the overall structural integrity, providing electrical insulation along the edges and improve the flexure strength of the solar cell.
