Abstract: A device and a method for detecting the ability of anti PID effect of a solar cell are disclosed according to embodiments of the invention. The device includes a static generator including a high voltage power supply and an ion stick connected to the high voltage power supply; and a metal tray under the ion stick. It is judged whether the solar cell has the ability of anti PID effect by detecting the solar cell directly by the device, so for determining whether the solar cell has the ability of anti PID effect, there is no need for a solar cell assembly manufactured by the solar cell.
