The WT-2000PVN is a table top measurement system, capable of performing a variety of measurements on PV cells, wafers, and blocks. The base system includes the overhead functions, and you configure the measurement capabilities to match your specific needs, by selecting from the options below.
WT-2010D
The WT-2000D is a complete measurement tool for monitoring quality of silicon blocks by measuring Carrier recombination lifetime and resistivity. The system provides fast, non-contact measurements (single-point, line scans and/or maps) on silicon blocks in size up to 210x210x500 mm. It has manual and automatic measurement modes and manual block loading capabilities.
Carrier recombination lifetime is a primary quality control parameter for multi-crystalline silicon blocks. The measurement is based on µ-PCD technique.
Resistivity is measured based on eddy current technique.
