Measurement System (Omni-Station-DSSC-IPCE) / Spectrometer systems
Omni-Station series is a multifunctional experimental platform which is based on Quantum Efficiency (QE) measurement
Measurement System (Omni-Station-DSSC-IPCE) summary
The system employs a turnkey integrated design, which can carry out the QE, Reflectivity, Mapping testing functions automatically. There are also Modularization Design special accessories to adapt to different solar cell samples.
Dye-sensitized solar cell’s incident photon-to-electron conversion efficiency (DSSC-IPCE) measurement is an essential characterization method for the photoelectrical performance of solar cells.

Testing method diversification: The testing solution could be DC mode or DC with bias light mode. The bias light was supplied from the 75W Tungsten-Halogen lamp. For the filters holders, one of the holder, the customer could fix different filters according to the bias light wavelength range. And for the other two filter wheels, each wheel has six positions, you can choose different filters to get different bias light intensity.
