Measurement Techniques

Paios performs a variety of different experimental techniques. Connect your device once, click once and everything is measured automatically.

paios-photo-celiv

Photo-CELIV is a powerful technique to extract charge carrier mobility, recombination and doping density.
Now OTRACE is included in Paios.


paios-impedance-spectroscopy

Impedance Spectroscopy is used to study charge carrier dynamics and charge trapping over a large range of time scales.


paios-capacitance-voltage

Capacitance-Voltage reveals information about the built-in field and the charge injection barriers. Doping density is extracted with Mott-Schottky analysis.


paios-transient-photovoltage-charge-carrier-lifetime

Transient Photovoltage (TPV) is frequently used to de- termine lifetimes of charge carriers in solar cells.
 


paios-dark-injection-transient

Dark Injection Transient (DIT) is used to study transport in mono-polar devices.


paios-imps-intensity-modulated-photocurrent-spectroscopy

Intensity Modulated Photocurrent Spectroscopy (IMPS) probes charge transport by a sinusoidal light intensity variation at short-circuit.

paios-TEL-transient-electroluminescence

Transient Electroluminescence (TEL) allows to extract mobilities and the phosphorescence lifetime in an OLED.


paios-current-volage-curve

IV & IVL are the standard characteri- zation techniques for solar cells and OLEDs.


paios-imvs-intensity-modulated-photovoltage-spectroscopy

Intensity Modulated Photovoltage Spectroscopy (IMVS) probes charge recombination by a sinousoidal light intensity variation at open-cirucit.

paios-transient-photocurrent

Transient Photocurrent (TPC) provides information on the charge carrier dynamics and charge trapping.


paios-charge-extraction

Charge Extraction estimates the charge carrier density of a solar cell at open-circuit voltage.


MELS-modulated-electroluminescense-spectroscopy

Modulated Electroluminescense Spectroscopy (MELS) probes charge transport in OLEDs on different frequencies.


OLED and PV Version

Paios is available in a version for solar cells and a version for OLEDs, either with LED illumination or with a photo-detector. Both versions can also be combined in one Paios.


Flexible Device Contacting

Flexible contacting of oleds and solar cells. Paios is delivered by default including probe tips, measurement table and a black lid to ensure measurements in the dark.

Flexible contacting of oleds and solar cells. Paios is delivered by default including probe tips, measurement table and a black lid to ensure measurements in the dark.

Our contacting probes are developed to create a low-resistance and reproducible contact to your device. With the magnetic feet they are flexible for different sample layouts. The device can be easily aligned using our alignment-tool.
The measurement table comes with a black lid to ensure measurements in the dark.

We also deliver a customized sample-holder upon request. See Paios Modules.

Integration of Simulation Software

Physical processes are often too complex to understand by qualitative explanations. Numerical simulation enables quantitative understanding of experimental results and can be used to put hypotheses under test. The drift-diffusion simulation software Setfos is seamlessly integrated into the Paios software.
Compare measurement and simulation directly in the Paios software.

Parameter Extraction with Automated Fitting

Many electrical parameters of organic or hybrid devices and materials (including perovskite solar cells) cannot be easily determined individually. Comprehensive device modelling is required to extract these parameters. Paios does the job for you. The parameter fitting routine optimizes simulation parameters to meet defined targets and calculates the parameter correlation to check the quality of the fit.
Use Setfos-Paios Integration to extract the following parameters:

  • Electron and hole mobility
  • Recombination efficiency or charge carrier lifetime
  • Charge injection barriers
  • Built-in voltage / HOMO / LUMO
  • Trap density
  • Trap depth
  • Doping density
  • Permanent dipole moments
  • Series resistance
  • Electrical permittivity
  • Emitter lifetime (OLED)
  • Photon to charge conversion efficiency (PV)

Paios performs global parameter fits on a combination of all available experiment types like capacitance-voltage, impedance, IV-curves, TPV, TPC, photo-CELIV. Our advanced algorithms make it possible to get fitting result within a few minutes. Parameter evolution and fit results can be monitored directly during optimization.
The fit quality can be analysed with the correlation matrix that is automatically calculated by Paios. The correlation matrix is important to judge how accurate the extracted parameters are.

The change of all parameters are displayed during the fitting.

Measurement and simulation are brought to agreement.

The correlation matrix shows the quality of the fit.
