LET YOUR ACCURACY SHINE! The Solar Reference Cell from VLSI Standards is designed for calibrating the irradiance of solar simulators used for testing solar cells and modules. The Solar Reference Cells consist of a 20 mm x 20 mm monocrystalline silicon Photovoltaic Cell encased in a 92 mm x 70 mm x 16 mm metal enclosure with a protective quartz window and a temperature sensor. The temperature sensor can be selected as either a Type K thermocouple or a 100 Ω platinum Resistance Temperature Detector (RTD).

Use the Silicon Nitride Film Thickness Standard (NFTS) to verify the accuracy of anti-reflective coatings as measured by single wavelength or spectroscopic ellips-ometers (SWE or SE) and reflectometers. Silicon nitride standards come in 4", 5", 6" round wafer formats and the certified nitride coating spans the range from 20 nm to 200 nm in thickness.

Use theResistivity Standards (RS) to verify the accuracy of the resistivity measurements for your starting material, and for doped layers, as measured by contact and non-contact resistivity measuring instruments. Resistivity standards come in a 3" round wafer format, and span the range of 0.002 to 75 ohm cm for resistivity, and 0.04 to 1500 ohm for sheet resistance.

Use the Step Height Standards (SHS) to verify the accuracy of the roughness measurements of your solar cells, as measured by mechanical or optical surface profilers. These standards consist of a 25 mm x 25 mm x 3 mm quartz block with a precisely etched uniform bar along with various test and diagnostic features. They span the range of 8 nm to 250 microns in height.*

*Step heights 100 microns and larger are mounted onto a 50mm x 50 mm x 5 mm anodized aluminum substrate.
