ACAP ANU adds further capabilities with Kelvin Probe Ambient-Pressure Photoemission Spectroscopy

ANU team with the new Kelvin probe at their Canberra campus labs

ACAP ANU has added powerful new characterisation capabilities to support its solar research, with the installation of a glovebox-integrated, ultra-high-vacuum Φ4 Kelvin probe system from KP Technology at its Canberra campus.

The system has the capability to measure a wide range of energetic properties of semiconductor absorbers and transport layers relevant for single junction and tandem solar cells of all materials classes, including work function, ionization potential / valence band energy / HOMO, surface band bending and bandgap, via Kelvin probe, surface photovoltage spectroscopy, and photoemission yield spectroscopy techniques. It is capable of measurements under vacuum or ambient pressure at temperatures from room temperature to 500°C, with automated spatial mapping of measured properties available via a motorized sample stage.

You can see it in action in the video here.

For collaboration enquiries, please contact the ANU team via Dr Lachlan Black.
