Solar cell PL imaging unit POPLI-3C
Light source for PL excitation compatible with 6-inch solar cells. By combining it with the EL image inspection device PVX series, PL observation becomes possible.
Free sample evaluation demo now available. POPLI is an advanced PL imaging device that adds a PL imaging unit as an option to the EL image inspection device PVX, achieving clear PL imaging and cost-effectiveness by utilizing the detection capabilities and software of the PVX.
basic information
Solar cells absorb light to generate electricity, but some of it is emitted through a phenomenon called luminescence. The method of capturing this light is called PL (Photoluminescence) observation. POPLI observes the emission wavelength range based on the bandgap. If there are defects, the generated carriers get trapped, resulting in a decrease in luminescence intensity compared to normal areas, allowing for the identification of abnormal regions based on the intensity difference.
