BLS/BCT: Bulk Silicon Characterization

Measure lifetime of bulk material prior to sawing with no surface preparation. Accurate measurement of bulk properties in both low- and high-lifetime material.


WCT-120: The Standard R&D Wafer-Lifetime Tool

Best available lifetime measurement accuracy. Measure lifetime and surface recombination for a wafer of any quality or crystallinity.

WCT-120TS: Temperature Dependent Lifetime Measurement

Wafer measurement instrument offering calibrated analysis of temperature-dependent carrier-recombination lifetime.

WCT-120PL: Wafer Lifetime Measurement with Photoluminescence Detector

Measure the calibrated carrier-recombination lifetime of a silicon wafer using both the standard method and the photoluminescence method.

IL-800: Inline Wafer Testing

Pre-process elimination of low-quality wafers using measured lifetime, trapping, and resistivity. Process control and optimization at dopant diffusion and nitride deposition steps.


FCT-650: Light I-V Testing for Solar Cells

Advanced analysis of solar cells including light I-V and Suns-Voc data. Capability to accurately measure high-efficiency conventional or backside-contact solar cells.

FCT-750: In-Line Light I-V Testing for Solar Cells

In-line, light I-V and Suns-Voc measurements in a single flash at 3600 units per hour. Capability to accurately measure high-efficiency conventional or backside-contact solar cells.

Suns-Voc: Post-Diffusion Process Control

Perfect for paste-firing optimization and process control. Open-circuit method indicates the upper bound of efficiency for any solar cell precursors.


FMT-500: Flash Module Tester

Measures any crystalline silicon module, including high- capacitance, high-effciency modules, using patented electronic-load technology. Results include Suns-Voc and I-V curves. Over 7 GW of product tested to date. Also ideal for R&D.
