Claim:
1. A method for manufacturing solar cells, comprising: prior to a metallization layer being applied to a first solar cell during a manufacturing of the first solar cell: applying the metallization layer to the first solar cell; determining whether the application of the metallization layer to the first solar cell has worsened the fill factor of the first solar cell; and based on the determined fill factor of the first solar cell and the determining of whether the application of the metallization layer to the first solar cell has worsened the fill factor of the first solar cell, altering intrinsic layer properties and deposition processes in a solar cell manufacturing process to obtain a solar cell with high fill factor, wherein the lifetime curve is determined using the following equation: where: τ is a lifetime value of the first solar cell; MCD is a minority carrier density of the first solar cell; W is a thickness of the first solar cell; and G is an optical generation rate of the first solar cell.
