摘要：

Lock-in PCR was introduced to investigate the industrial solar cell. Laser-induced infrared photocarrier radiometry (PCR) is a dynamic near-infrared (NIR) modulated photoluminescence imaging (PL), which has proven to be an effective non-contact methodology for tie measurement of transport properties in semiconductors. Lock-in carrierography (LIC) is a dynamic NW InGaAs-camera-based photocarrier radiometric PL imaging method recently introduced as an imaging extension of PCR Ten industrial multicrystalline solar cells were used for LIC measurements. Statistical distributions were obtained from the infrared images and the dependencies of the efficiencies on the statistical parameters were found. Experimental results show that the statistic parameters in lock-in PCR could be used for the index of efficiency of solar cells.
