Front Cover: Transparent Near‐IR Dye‐Sensitized Solar Cells: Ultrafast Spectroscopy Reveals the Effects of Driving Force and Dye Aggregation (ChemPhotoChem 3/2024)

The Front Cover highlights one of the main ultrafast spectroscopic techniques used to study the light-induced molecular processes in transparent solar cells based on diketo pyrrolopyrrole dyes. A near-IR pump pulse excites the molecules, and photoproducts like cations and excited dye aggregates are probed by a white-light pulse. Cover design by J. Valanciunaite (Strasbourg). More information can be found in the Research Article by Frédéric Sauvage, Fabrice Odobel, Stefan Haacke and co-workers.
