Wavelength Response/ IPCE/IQE/EQE

For measurements of relative and absolute spectral response resp. quantum efficiency of solar cells. Spectral range 300 nm —3000 nm (or as desired), cell size up to 4 x 4 cm2 . Specialised bias light adapters for tandem cells or concentrator cells available,For the determination of solar cell parameters, such as diffusion length, recombination velocity, thin film spectral transmission and others,For determination of spectral mismatch factors for subsequent calibration of cells in solar simulators (simulator lamp spectrum and reference cell SR required).
