Abstract

See how our hyperspectral imaging platform IMA continues to assist the photovoltaic community in this paper by Schultz et al. : «Absolute calibrated hyperspectral photoluminescence (PL) imaging is utilized to access, in a simple and fast way, the spatial distribution of relevant solar cell parameters such as quasi-Fermi level splitting, optical diode factor, Urbach energies Eu, and shunt resistances Rsh, without the need for electrical measurements.»


IMA is a unique comprehensive analysis system for solar materials.
