Facilities

Our research facilities and equipment span a range of sectors and disciplines and allow us to carry out cutting-edge energy research. Below are the facilities available to our staff and students that can be use as part of collaborative research projects.

Offshore and marine energy facilities

Falmouth Bay test site (FaBTest)

FaBTest is a pre-consented test area for offshore renewable energy, located within Falmouth Harbour and with easy access to the extensive port infrastructure. This 2.8km2 nursery facility is sheltered from the extreme sea conditions experienced at other test sites, and thus enables device developers to test components, concepts or full-scale devices in a moderate wave climate.

The site offers water depths of 20m-50m and seabed types of rock, gravel and sand, and its pre-consented status enables a fast, flexible, low risk and low cost solution for the testing of marine energy technologies, components, moorings and deployment procedures.

Science and Engineering Research Support Facility (SERSF)

The SERSF building is home to offshore renewables laboratories, and also features a specially designed area for business engagement called ‘The Collaboratory’. 

Renewable Energy Engineering Facility (REEF)

Currently under construction, the Renewable Energy Engineering Facility (REEF) will provide a number of exciting opportunities for students on the Renewable Energy programmes. The building will house an engineering workshop where students will be able to design, build and test projects to support their studies. The facility will also have operational renewable energy technologies that students will be able to conduct experiments on or compare the outputs of with their simulations and calculations.

Engineering laboratory

Experiments and demonstrations of the fundamental engineering principles are run in the Engineering laboratory in the Daphne Du Maurier building. With equipment demonstrating the generic engineering concepts as well as renewable energy specific technologies the lab supports modules in all years of the programme.

Potentiostats

These allow fundamental electrochemical testing on small laboratory scale components and cells using techniques such as cyclic voltammetry, linear sweep voltammetry, electrical impedance spectroscopy and chronoamperometry. The application of these techniques allows novel electrodes, electrolytes, catalysts and full cell systems to be developed and optimised at small scale, before integration and scaling up for commercialisation.

Rotating electrodes

Currently two rotating electrode geometries are available: rotating disc electrode (RDE) and rotating ring disc electrode (RRDE). This equipment is especially useful for studying the kinetics of the chemical reactions involved in batteries, electrolysers and fuel cells.

Scanning electron microscope

Imaging samples processed with this equipment allow for the characterisation of morphologies of materials such as catalysts under development and depositions made in battery systems. This facilitates the development of catalysts and high-performance battery systems by, for example, identifying the effect of system additives or electrode material on deposit morphology.

Solid polymer electrolyte water electrolyser

This facility is a laboratory scale water electrolyser which enables the development of efficient, stable catalysts for both the anode and cathode and performance and stability testing of novel catalysts and electrodes in a fully functional system.

Laboratory scale redox flow batteries

The use of laboratory scale cells, with electrode areas of 1cm2 and 25cm2, facilitate cycling and stability testing on a range of redox flow battery chemistries, and allow for performance testing of novel materials, electrolyte compositions, electrode structures and flow regimes in a full cell redox flow system.

Large area continuous solar simulator

The WACOM (Continuous) Solar Simulator is used for evaluation of properties of solar cells and small sized modules. This system irradiates continuous light, which is similar to sunlight in spectral distribution (A.M.1.5) and intensity (1Sun), over a 210 x 210mm area.

Combined with a 5D rotational table, this enables the creation of environmental conditions anywhere on the planet within 10-80 degree latitudes. The computer-controlled simulator automatically adjusts the solar radiation and position of the sun during the day and time of the year, to create conditions related to the given location on the earth.

Solar simulator - Flash

The Flash type Pasan SunSim Solar module tester is one of the first of its kind in the UK. Having a Class A+A+A+ certification, it is two times better than the best class A solar simulators. The equipment is used for testing standard crystalline silicon-based modules, as well as new technologies like the thin-films. It is capable of testing solar modules up to 2m x 2m.

Impedance spectroscopy (IS)

Impedance spectroscopy can be used to:

  • distinguish between two or more electrochemical reactions taking place,
  • view diffusion through a passive film,
  • provide information on the capacitive behaviour of the system,
  • and provide information about the electron transfer rate of reaction.

In our solar lab, Metrohm Autolab impedance spectroscopy is used to monitor the corrosion or discharge of fuel cells and investigate the properties and quality of dye-sensitised and perovskite solar cell devices.

External quantum efficiency (EQE) / Internal quantum efficiency (IQE)

EQE and IQE reveal the cell performance for a particular wavelength. The PVE300 system from Bentham enables us to obtain EQE and IQE for solar cells. The PVE300 is fully automated through the USB interface and controlled by the Benwin+ windows software. It directly reports measurement results including spectral response, EQE, IQE and AM1.5 for all types of photovoltaic devices and architectures: c:Si, mc:Si, a:Si, µ:Si, CdTe, CIGS, CIS, CZTS, Ge, dye-sensitised, organic/polymer, multi-junction (2-, 3-, 4– junctions and more), quantum well, quantum dot, chalcogenides and perovskites.

Spectrophotometer

A spectrophotometer measures the reflection or transmission properties of a material as a function of wavelength. The LAMBDA 1050 UV/Vis/NIR has potential to measure 175 nm to 3300nm wavelength. It is capable of achieving a greater level of sensitivity, resolution and speed in the NIR (800-2500nm) range, and simplifies the analysis of difficult samples such as high absorbing glass, optical coatings or thin film filters.

SOPRA ellipsometer

Ellipsometry is a method based on measurement of the change of the polarization state of light after reflection at non normal incidence on the surface to study. The system helps in carrying out photometry including Transmission, Reflection, Scatterometry, and luminescence measurements. All measurements are made automatically as a function of: wavelength, angle of incidence, polarization state and time. Standard spectral range is 230-900nm, and can be extended in both DUV and NIR regions.

Gas chromatography

The Clarus 580 Gas Chromatograph is used for qualitative and quantitative analysis of solar fuel and environmental pollutants. The Gas Chromatograph (GC) is a highly responsive piece of equipment, which is able to detect small traces of gas molecules in small volumes injected into the GC column (which is a molecular sieve). The gasses are separated by the column based on retention time due to the size of the gas molecules and then are detected by a detector producing a graph. An inert gas (argon) is used as the mobile phase to pass the sample through the column (a solid stationary phase). We use the GC to detect if any hydrogen is being produced in our water splitting reactions.

Smart grid setup

Grid voltage support during symmetrical and asymmetrical AC faults, and protection and fault isolation during DC faults are significant challenges for converter operations and control in order to deliver a highly reliable, versatile community energy solutions.

We offer real-time micro grids (DC or AC) for simulators, which can implement a host of commands and control algorithms in any DG convertor to replicate the real time loads, and analyses the performance of the micro grid in real time.

Photo/Electro-luminescence set

This set-up utilises the electro-luminescence phenomenon to image micro cracks, cell failures and in-homogeneities of wafers and solar cells which are extremely difficult to detect visually. The equipment was developed for research and off-line solar inspection, therefore detailed quality control is enabled.

Differential scanning calorimeter (DSC)

DSC is used for thermal characterisation of materials including polymers. DSC can detect melting temperatures and enthalpies (heats of fusion), crystallization temperatures and enthalpies, glass transition temperatures, oxidative-induction time (OIT) and oxidative onset temperature (OOT), degree of crystallinity, reaction temperatures and enthalpies, cross-linking reactions (curing), degree of curing, specific heat capacity, distribution of molecular weight (peak shape). The process involves sample preparation, evaluation and interpretation of the resulting curves. We offer the DSC 214 Polyma from Netzsch.

Outdoor test facilities

Our outdoor test facilities comprise a sun tracker (SOLYS) to measure direct and diffuse solar radiation, weather station (MetPak Pro) to measure wind speed and humidity, high spec IR (infrared) cameras, calibrated solar cells and sun sensors. A south facing and inclined (local latitude angle) test rig for photovoltaic (PV) devices enables outdoor experiments and measurement of PV power throughout the year.

SOLYS can be configured as a complete solar monitoring station with up to three ventilated radiometers. The MetPak Pro Base Station features an on-board barometric pressure sensor temperature/humidity probe essentially used for weather monitoring. We have Kipp and Zonnen type pyranometers for sun sensor and a dual axis large area (6m by 6m) solar tracker.

Computational faculties

The Solar Energy group has access to various computational modelling software. This includes Computer Aided Design, Finite Element Analysis, Optical ray tracing and basic programming. Special software for carrying out the PV system analysis is also available to model the available solar radiation at any given location and identify the PV power outputs we can achieve through it. These include:

  • Optical ray tracing (ASAP, APEX)
  • Finite element (COMSOL, ANSYS)
  • Cad (Solid Works)
  • PV software (PVSYST, TRNSYS)
  • Programming (MATLAB)
