Accurate flash testing of high-efficiency solar cells and modules with QuickSun solar simulators using Capacitance Compensation (CAC). High-efficiency solar cells – such as passivated emitter and rear contact (PERC) cells, heterojunction technology (HJT) cells, and interdigitated back-contact (IBC) cells – are currently gaining in production volume and market share. However, the solar simulators used in many manufacturing lines cannot accurately measure the maximum power and other characteristics of these devices. Typically, maximum power is underestimated, causing manufacturers to sell their products with lower power, and thus lower price, than necessary.

Spectral match of QuickSun 550CE is class A+ according to both editions of the standard IEC 60904-9. The new parameters on spectrum quality are calculated on the left. The graph shows spectral deviation is green (positive deviation) and red (negative deviation).
