Solar Cell IV Tester

Advanced Solar Cell IV Tester

Engineered for Precision and Efficiency in Solar Cell Production

Our Advanced Solar Cell IV Tester is a cutting-edge solution designed for high-accuracy electrical performance testing of monocrystalline and polycrystalline silicon solar cells. Integrating industry-leading optical simulation and data acquisition technologies, this tester ensures rapid detection, classification, and recording of key electrical parameters, driving quality control in modern solar panel production lines.

Technical Features

1. Industry-Leading Optical Simulation System

• A++ Spectral Performance: Exceeds IEC60904-9 standards with spectral matching accuracy within ±2% (300–1200 nm), ensuring true-to-nature simulation of sunlight conditions for reliable testing of PERC, HJT, TOPCon, and other advanced cell types.
• Ultra-Stable Irradiation: Pulse xenon lamp delivers 70–120 mW/cm² adjustable irradiance, with uniformity ≤±2% and stability ≤±2%, eliminating measurement drift caused by light fluctuations.
• Long-Pulse Flexibility: Flash duration adjustable from 10–100 ms, compatible with high-capacitance cells (e.g., bifacial/heterojunction) to avoid capacitive effects.

2. Precision Measurement & Intelligent Compensation

• 14-Bit Quad-Channel Synchronized Acquisition: Captures over 8,000 I-V/P-V curve data points in a single scan, enabling granular analysis of cell performance anomalies (e.g., Rs/Rsh deviations, hot spots).
• Four-Wire Kelvin Measurement: Minimizes contact resistance errors, achieving voltage resolution of 1 mV and current resolution of 1 mA across 0.1–5 W power ranges.
• Dynamic Auto-Compensation: Real-time temperature correction via infrared sensors (0–50°C ±0.1°C) and irradiance calibration, ensuring STC-compliant results under variable environments.

3. Robust Engineering for Industrial Durability

• Zero-Damage Contact Design: Pneumatic buffered probes with soft-landing technology reduce breakage rates to ≤0.05%, while non-scratch pins maintain cell integrity during 24/7 operation.
• Seamless Automation Integration: Voice-guided operation, Excel/CSV export, and LIMS connectivity support batch processing (3 sec/cell) and automatic grading into 16 bins.

Quality Assurance & Application Value

• Defect Detection Reliability: Identifies micro-cracks, resistance anomalies, and efficiency degradation with >98% accuracy, directly enhancing cell yield.
• Future-Proof Compatibility: Supports 166/182/210 mm wafers and busbar-free designs, adapting to next-generation cell architectures.
• Low-Cost Ownership: Xenon lamp lifespan of 300,000 flashes minimizes maintenance, while modular design allows EL/PL functional upgrades.

Ideal for solar cell manufacturers prioritizing precision, this tester bridges R&D innovation and mass production by delivering laboratory-grade data at production-line speeds. Its synergy of spectral accuracy, contact safety, and smart analytics sets a new benchmark in IV testing economics.
