Microscopic PL observation of the fine structure of wafers in the solar cell manufacturing process.
The PVX1000+POPLI-μ allows for photoluminescence observation of the fine structures of wafers during the solar cell manufacturing process using a microscope. In the case of PERC, it is possible to evaluate individual Local-BSFs based on PL intensity and assess the damage to the passivation layer around the laser contact holes. Additionally, by using a DC power supply for EL observation of the modules, it is possible to pinpoint the locations of defects.
