The growing interest among PV module manufacturers in commercializing perovskite-based modules highlights the increasing need for advanced, reliable characterization tools, particularly during the research and development (R&D) phase.
In line with this trend, WAVELABS Solar Metrology Systems GmbH promoted its latest SINUS-1000 ADVANCED mini-module tester at SNEC 2025. While designed primarily for wafer-based cell technologies, this new platform also supports thin-film PV solutions, especially perovskite-based modules.
To meet the stringent irradiance quality standards required for accurate perovskite cell characterization, the SINUS-1000 ADVANCED uses LED-based light sources that provide A+ class homogeneity, ensuring highly uniform light distribution over a 50 × 50 cm illuminated area. The tool is optimized not only for crystalline silicon cells but also for tandem cells, which integrate 2 or more sub-cells made of different materials (e.g., perovskite + silicon) to capture a wider portion of the solar spectrum. For example, one sub-cell may absorb short-wavelength (blue) light, while another targets long-wavelength (red/infrared) light.
To support this architecture, the system incorporates automated spectral calibration for each sub-cell, enabling current mismatch tuning and maximum power point (MPP) tracking of tandem structures. WAVELABS notes that the system’s smart spectral calibration supports a broad range of exposure durations, including continuous illumination, which is essential for advanced testing.
To ensure long-term spectral stability, the tool integrates both a spectrometer and an intensity sensor operating within a closed-loop feedback system, providing consistent and accurate measurement conditions.
At the R&D level, accurate characterization of perovskite and tandem modules requires multiple diagnostic capabilities. The SINUS-1000 ADVANCED integrates all critical characterization functionalities into a single platform. These include IV Measurements, assessing current, voltage, and power under standard test conditions (STC), External Quantum Efficiency (EQE) – measuring how efficiently each sub-cell converts incoming photons into electrons, Electroluminescence (EL) – Identifying defects such as microcracks or inactive cells; particularly well-suited for tandem cell testing, and Infrared (IR) Imaging – Detecting thermal anomalies like hot spots or mismatches. Additionally, the system is capable of measuring module performance under varying irradiance and temperature conditions, in full compliance with IEC 61853-1 standards.
To protect sensitive solar devices during testing, the system features vacuum suction-based handling and precise thermal management, minimizing physical stress and thermal variation while maintaining high-quality measurement performance.
