Eternalsun Spire has developed an AAA+ High-Performance Light Soaker (HPLS) with extremely accurate temperature control and in-situ IV characterization. The system combines AAA+ class steady-state illumination (IEC 60904-9 ed. 3) and extremely accurate and uniform temperature control from 25 to 95 C.

The HPLS enables the study of degradation effects that potentially predict overtime underperformance of solar plants simulating real-life conditions. It can measure the metastability of thin-film modules such as CIGS, CdTe, GaAs; accurately perform IV measurements of OPV, perovskite and tandem cells; perform temperature coefficient and energy rating measurements.

Humidity control can be added.
