The MCT10-300-20T Multi-Channel PV Module Steady-State Testing System is a high-throughput platform designed to evaluate the illumination stability, temperature reliability, and long-term electrical performance of thin-film, perovskite, and tandem PV modules. Equipped with a 3A-grade LED steady-state solar simulator, independent temperature-controlled channels, and a flexible multi-mode testing platform, the system supports continuous I-V scans, MPPT tracking, and degradation monitoring under precisely controlled conditions.
The Multi-Channel PV Module Steady-State Testing System accommodates module sizes from 50×50 mm to 300×300 mm, covering perovskite small cells, mini-modules, and flexible devices. The simulator supports selectable spectral ranges (300–1100 nm / 300–1200 nm), adjustable irradiance (100–1100 W/m²), and calibrated AM1.5G matching to ensure measurement accuracy.
Module Compatibility Table
| Supported Size | Dimensions (mm) | Substrate Type |
|---|---|---|
| Small Cells | 50×50 | Glass / Flexible |
| Mid-Size | 158×158 | Glass / Flexible |
| Mid-Size | 220×220 | Glass / Flexible |
| Mini-Modules | 300×300 | Glass / Flexible |
The testing platform integrates high-precision lifting and sliding mechanisms. The lifting module adjusts the light-source height from 10–40 cm with 0.1 cm resolution, while the horizontal sliding platform switches between multi-channel mode (up to 20 channels) and single large-module testing.
The LED steady-state solar simulator delivers industry-standard 3A performance, ensuring accurate optical exposure for long-duration stability studies.
Illumination Performance Table
| Parameter | Specification |
|---|---|
| Spectral Range | 300–1100 / 350–1100 / 300–1200 / 350–1200 nm |
| Irradiance Range | 100–1100 W/m² |
| Uniformity | ≤2% |
| Temporal Instability | ≤±2% |
| Spectral Match | A / A+ |
| Adjustable Distance | 10–40 cm (0.1 cm precision) |
| LED Lifetime | 10,000 h |
The combination of adjustable irradiance, high uniformity, and low time instability ensures that all modules experience consistent, repeatable illumination—an essential condition for light-soaking stability experiments in perovskite and thin-film PV research.
The system incorporates independent electrical source-measure units (SMUs) enabling simultaneous multi-channel testing without interference between channels. Each channel supports individual I-V sweeps, MPPT algorithms, and continuous monitoring of critical PV parameters.
Multi-Channel Electrical Specifications
| Electrical Item | Multi-Channel | Single Channel | Perovskite Single |
|---|---|---|---|
| Voltage Range | 10 V / 18 V | 80 V | 100 V |
| Current Range | 0.5–1 A | 20 A | 1 A |
| Min Voltage Range | 1 V | 10 V | 300 mV |
| Min Current Resolution | 5 μA | 1 mA | 100 nA |
| Accuracy | 0.1% | 0.1 mV / 0.1 mA | ±(0.025%+0.025%FS) |
This wide measurement range supports:
Perovskite pixel-level devices
Tandem mini-modules
High-current crystalline-silicon modules
The system allows each device to operate with its own electrical parameters, enabling realistic performance benchmarking across different material systems.
Each testing position integrates a dedicated heating plate with feedback-controlled thermal regulation that maintains stable and consistent temperatures, ideal for accelerated aging and thermal drift studies.
Temperature System Table
