Simple and accurate contactless measurement of true bulk silicon lifetime and resistivity on CZ or multicrystalline silicon bricks and ingots. Measure the true lifetime of bulk material prior to sawing with no surface preparation required.
The standard R&D tool for process optimization with the best available measurement accuracy. Measure initial material quality, surface passivation, and dopant diffusion. MX version that is capable of measuring samples up to 230 mm is also available.
Wafer lifetime measurement instrument offering calibrated analysis of temperature-dependent carrier-recombination lifetime over a temperature range of 25-200°C. Same great R&D level analysis as the WCT-120 with the added ability to analyze the temperature dependence of the key characteristics of the sample including defects.
Measure the calibrated carrier-recombination lifetime of a silicon wafer using both the standard method (QSSPC) and the photoluminescence (QSSPL) method.
Advanced R&D level wafer analysis for high throughput inline production environments. Pre-process elimination of low-quality wafers using measured lifetime, trapping, and resistivity as well as process control and optimization at dopant diffusion and nitride deposition steps.
Advanced R&D analysis of solar cells including light I-V and Suns-Voc data. Capability to accurately measure multiple cell designs with the standard front contact chuck or interchangeable custom chucks.
Inline, light I-V and Suns-Voc measurements in a single flash at 4800 units per hour. Capability to accurately measure high-efficiency conventional or backside-contact solar cells.
Perfect for paste-firing optimization and process control. Open-circuit method indicates the upper bound of efficiency for any solar cell precursors.
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 20 GW of product tested to date. Also ideal for R&D.
