IV testing marks the final quality and performance verification step in solar cell manufacturing. As cell architecture evolves toward TOPCon, HJT, and tandem structures, testing systems are increasingly required to deliver higher spectral accuracy, stability, and diagnostic depth, driving innovation in light sources, measurement capabilities, and tool design. For the latest TaiyangNews Market Survey On Solar Cell Production Equipment 2025, we have received data from 2 companies – WAVELABS Solar Metrology GmbH and HALM.
WAVELABS has expanded its SINUS product line with the addition of 2 new systems – SINUS-360 PRO and SINUS-360 ADVANCED – in addition to the updated version of the SINUS-300 PRO. All 3 models feature LED-based light engines. In addition to IV characterization, they are also capable of bifacial measurements and fine spectral tuning. The SINUS-360 ADVANCED serves as the high-end lab solution with an illumination area of 260 × 260 mm. The tool comes with integrated capabilities for electroluminescence (EL), photoluminescence(PL), infrared (IR) imaging, and cut-cell testing.
For production environments, the SINUS-360 PRO is engineered for high-throughput lines, capable of testing up to 12,000 cells per hour. The updated SINUS-300 PRO, now featuring an A+AA++ rating, supports a throughput of up to 4,000 cells per hour. It also offers additional key diagnostic features such as EQE and red-blue response measurements. SINUS-70 ADVANCED, on the other hand, continues to cater to small-area research applications, with its A++AA++ rating over an illumination area of 51 × 51 mm.
