This work presents a new multi-laser LBIC measurement system that is currently under development at CREST. The final set-up uses 11 lasers, 6 of which are currently operational, to form a spatially resolved spectral response map of the device under test. The design aspects of the measurement system are detailed and first measurements of a crystalline and amorphous silicon solar cell are demonstrated. Measurements show how a crack in a crystalline silicon solar cells affects the local quantum efficiency and the effects of discoloration in amorphous silicon. Thus, highlighting the advantages in multi-wavelength and absorption depth profiling of device performance and defects.
