Front Cover in Advanced Energy Materials
Our publication on assessing ion migration in fully printed perovskite solar cells received the front cover of Advanced Energy Materials, one of the best journals in materials science!
The cover art visualizes how light of different wavelength penetrates with varied depth due to a spectrally dependent absorption coefficient, which decreases towards the red. We exploit this effect in spectral photocurrent measurements (EQE) dependent on voltage prebias conditions to analyze photocurrent losses related to mobile ions in mesoscopic perovskite solar cells with Carbon electrode.
