Lab 3 is maintained to clean room standard and houses equipment for analysis and characterisation of optical and surface properties. The equipment includes an ellipsometer, laser measurement of surface roughness, a Quantum efficiency chamber and UV-IR-vis spectrophotometer. This laboratory is largely used for analysis of photovoltaic solar cells and wafers.

Ellipsometer (WVASE32) for non-destructive testing of surfaces, interfaces and thin films.

Optical Profilometer (Veeco NT9080) used for surface roughness characterisation.

Quantum efficiency chamber for testing the response of solar cells under controlled spectra.

Perkin-Elmer Lambda 950 UV-Vis spectrophotometer, able to take whole solar cells (156 mm)

FTIR (Fourier Transform Infra Red Spectrometer) (Vertex 70) used for chemical characterisation,
