Spectra-Solaris Laboratory

Spectra-Solaris Solar Cell Dark Test  capability is based on a precision set-up allowing in-depth solar cell analysis and determination of solar cell main parameters based on the well established two-diode model of the solar cell. The instrumentation is capable of characterizing a diverse range of solar cell parameters, including cell  complete dark I-V curves, series resistance Rs, shunt resistance Rsh, diodes ideality factors n1 and n2, saturation currents Jo1 and Jo2. The design, modular in nature, can be easily customized.

This state-of-the-art system has been designed while keeping in mind the specific needs of the present day solar industry. Anyone performing in-depth solar cell technology development or experimental research will benefit from the flexibilty, accuracy and breadth of testing capabilities as required by or even exceeding IEC, ASTM and JIS standards.

Technology:

Spectra-Solaris Laboratory dark I-V measurement set-up is able to perform precision current measurements using a source-meter for low currents or a programmable electronic load for high currents.
