measurement systems allow users to quantify the performance of photovoltaic
cells. Quantum efficiency focuses on the proportion of the incident photons
applied to the cell that are successfully collected.
Sciencetech's PV Testing System (PTS) is a cost-effective complete TurnKey system. It allows measurement for solar cell testing and characterization:
Defined as the ratio of the number of carriers generated and collected by the solar cell to the number of photons of an incident beam without considering the losses due to reflection, transmission, or absorption from the sample
A calculation of the QE with consideration of the losses at the sample, i.e., the ratio of the number of carriers generated and collected by the solar cell to the number of photons that are truly converted by the solar cell.
All Sciencetech systems incorporate adherence to industry standards. Sciencetech PV Testing System equipment are designed and manufactured according to:
Test cell included for verification (SCI-REF-NL). SCIENCETECH include a complete Quality Control Report including test results (Calibration, Spectral response, quantum efficiency and IV measurements)
The system includes all required high quality Instruments to perform these measurements:
The PTS systems come with a light-tight sample chamber to perform measurements in optical isolation. This shielded and light-tight test area enclosure has a convenient removable cover allowing access from the top, front and sides.
Sciencetech Inc. designs and manufactures five different variants of Quantum Efficiency Measurement System (PTS), as shown in the following table, for implementation of different experimental methods: External and Internal Quantum Efficiency (EQE and IQE), Constant Photocurrent Method (CPM), Dual Beam Photocurrent Method (DBP) and Steady State Photo Conductivity (SSPC).
