Assessing Transient Measurement Errors for High-Efficiency Silicon Solar Cells and Modules

High-efficiency silicon solar cells are well known to have high “capacitance,” in the sense of having a slow time response to changes in voltage or current. This is often seen during power measurements of cells or modules. This issue is increasingly important as high-efficiency cells such as p-type passivated-emitter rear contact (PERC) and n-type heterojunction cells become more common within the...
