Abstract
A method of high reverse current burn-in of solar cells and a solar cell with a burned-in bypass diode are described herein. In one embodiment, high reverse current burn-in of a solar cell with a tunnel oxide layer induces low breakdown voltage in the solar cell. Soaking a solar cell at high current can also reduce the difference in voltage of defective and non-defective areas of the cell.
