Photovoltaics and Materials Testing

Photovoltaic Testing Systems (PTS) are complete, turn-key systems; however, any PTS can be customized to meet your unique requirements. Scroll down to see what systems are offered or download the brochure for the PTS series here: PTS Brochure File-1548168373

These are the variants of the Photovoltaic Testing System (PTS):

PTS-2-QE Quantum Efficiency Measurement System (see specs).

PTS-3-CPM Constant Photocurrent Method System (includes PTS-2-QE capability); The CPM system illuminates the sample solar sell with a bias solar light source while a separate light source is modulated to cover a specified spectrum.

PTS-3-DBP Dual Beam Photocurrent Method System (includes PTS-2-QE capability); The DBP system is based on maintaining constant photocurrent over the range of photon energy to get constant quasi-Fermi levels

PTS-3-PTD Photothermal Deflection System (includes PTS-2-QE capability); The PDS system utilizes the photothermal deflection spectroscopy method allowing for the direct measurement of the sub-gap absorption of the sample by utilizing the mirage effect.

PTS-4-SSP Steady State Photoconductivity System (includes PTS-2-QE capability); The steady state photoconductivity measurements give information about the nature of defects, mobility-lifetime products, and the transport and recombination kinetics of photogenerated carriers

Notes:

There is also an optional upgrade for IQE (Internal Quantum Efficiency) measurements for any of these systems.

The PTS- series is designed and manufactured by Sciencetech, Inc. (Canada).
