Quantum efficieny

The PVE300 is a turnkey solution for the determination of solar cell spectral response/

EQE (IPCE) and IQE. A range of options include mounts for substrate, superstrate or packaged devices, integrating sphere accessory for measurements of total reflectance and transmittance, a choice of single or multiple channel bias sources, including an AM1.5 matched bias source and a motorised XY stage for device mapping.

Fabrication step: Micro and nano fabrication
Purpose: Characterization of solar cell spectral response/EQE (IPCE) and IQE.
Material systems: Polymers, organics, dielectrics, metals and semiconductors
Node: Materials
Specifications/resolution: The standard spectral range of 300-1100nm, may be extended to 1800 nm and beyond

Solar Simulator

A Solar Simulator is a light source that approximates the illumination of natural sunlight. Solar simulators with various tailored spectral output are used to to test a variety of samples including but not limited to solar cells, sun screen (SPF), materials photo-stability, and other samples (in-vivo or in-vitro) under controlled, repeatable, laboratory conditions.

Fabrication step: Micro and nano fabrication
Purpose: J-V curves of solar cell devices as well as long-term stability test under illumination.
Material systems: Polymers, organics, dielectrics, metals and semiconductors
Node: Materials
Specifications/resolution: Factory certified Class AAA CW solar simulator

Potenciostat

SP-300 is a 500 mA to 10 A state-of-the-art research grade potentiostat/galvanostat/EIS with remarkable specifications such as 7 mHz max frequency, floating mode, analog filtering, built-in calibration board, and stability bandwidths.

The SP-300’s modular chassis accept an optional high current/high voltage option board.

Alternatively, the SP-300 can accept a second potentiostat board (either standard or EIS) and perform as a Bipotentiostat to perform RRDE experiment. It is also a multiple user system as each channel board can be used independently by two different researchers.
