DC, AC and Transient Characterization of OLEDs and Solar Cells
Photo-CELIV is a powerful technique to extract charge carrier mobility, recombination, and doping density.
Now OTRACE is included in Paios.
Impedance Spectroscopy is used to study charge carrier dynamics and charge trapping over a large range of time scales.
Capacitance-Voltage reveals information about the built-in field and charge injection barriers. Doping density is extracted with Mott-Schottky analysis.
Transient Photovoltage (TPV) is frequently used to determine charge carrier lifetime in solar cells.
Dark Injection Transient (DIT) is used to study transport in mono-polar devices.
Intensity Modulated Photocurrent Spectroscopy (IMPS) probes charge transport by a sinusoidal light intensity variation at short-circuit.
Transient Electroluminescence (TEL) allows extracting mobilities and the phosphorescence lifetime in an OLED.
IV & IVL are the standard characterization techniques for solar cells and OLEDs.
Intensity Modulated Photovoltage Spectroscopy (IMVS) probes charge recombination by a sinusoidal light intensity variation at open-circuit.
Transient Photocurrent (TPC) provides information on the charge carrier dynamics and charge trapping.
Charge Extraction estimates the charge carrier density of a solar cell at open-circuit voltage.
Modulated Electroluminescence Spectroscopy (MELS) probes charge transport in OLEDs at different frequencies.
An overview of all characterization techniques for solar cells can be found in our tutorial “Characterization of Perovskite and Organic Solar Cells”.

OLED and PV Characterization
Paios is suitable for the characterization of both solar cells and OLEDs.
The versatile Combined Version is suitable for research and development on both LEDs and photovoltaic devices.
SOLAR CELLS: the main hardware is equipped with a suitable LED illumination system. A multi-LED board can be employed for External Quantum Efficiency (EQE) measurements. For fast transient measurements, a nanosecond pulser module is also available.
OLEDs: an amplified photo detector with auto gain is included in the version for OLED research. A fiber-coupled spectrometer for spectral emission characterization of OLEDs is also available.
