Abstract

In order to detect the monochromatic light intensity during the hydrogen passivation process for silicon solar cells , a method was developed to measure and convert the photon flux density data of the monochromatic light to the standard solar irradiation. Meanwhile, a test device was designed based on Freescale ARM Micro controller. A standard solar cell chip was used as a detector, the acquired signal will be converted to standard solar illumination and the result will be shown on the OLED screen finally. The experim ent showed that the device can precisely test the monochromatic light photon flux density..
