QUANTIFICATION OF SPATIAL INHOMOGENEITY IN PEROVSKITE SOLAR CELLS BY HYPERSPECTRAL LUMINESCENCE IMAGING
In this manuscript, state-of-the-art p-i-n perovskite solar cells are analyzed by hyperspectral luminescence imaging. We investigated spatial fluctuations from few micron to the millimeter scale and compare samples having different hole blocking layers to understand the role of the front contact. To go further in the analysis we applied three different theories describing luminescence emission, i.e. spatially resolved absolute quasi-Fermi levels splitting from PL, from EL, as well as the carrier collection efficiency

HYPERSPECTRAL MULTIPLEX SINGLE-PARTICLE TRACKING IN LIVE NEURONS
To improve our capability to investigate complex mechanisms of synaptic signaling and remodeling, we designed a fluorescence hyperspectral imaging platform to simultaneously track different subtypes of individual neurotransmitter receptors trafficking in and out of synapses. This imaging platform allows simultaneous image acquisition of at least five fluorescent markers in living neurons with a high-spatial resolution.

HYPERSPECTRAL STUDY OF PEROVSKITE
The search for flexible, cheap, and easy to process photovoltaic materials took a new turn in the past years with the rapid evolution of organometallic perovskite solar cells. If research groups want to take to the market this new star of photovoltaics, a better understanding of the photophysics and the degradation mechanisms is essential. Photon etc’s global hyperspectral imaging platform (IMA™) is perfectly suited to find the answers to the questions scientists have been asking themselves about perovskite’s outstanding properties.
