Quantifying Charge Extraction and Recombination Using the Rise and Decay of the Transient Photovoltage of Perovskite Solar Cells
Krückemeier, L., Liu, Z., Kirchartz, T. and Rau, U. Adv. Mater. 2023, 35, 2300872 The extraction of photogenerated charge carriers and the generation of a photovoltage belong to the fundamental functionalities of any solar cell. These processes happen not instantaneously but rather come with finite time constants, e.g., a time constant related to the rise […]

Air Processing of Thick and Semitransparent Laminated Polymer: Non-Fullerene Acceptor Blends Introduces Asymmetric Current-Voltage Characteristics
Rodríguez-Martínez, X., Hartnagel, P., Riera-Galindo, S., Beket, G., Österberg, T., Gao, F., Kirchartz, T., Inganäs, O. Adv. Funct. Mater. 2023, 33, 2301192 Non-fullerene acceptors have recently revolutionized indoor organic photovoltaics (OPVs) with power conversion efficiencies exceeding 30% in laboratory scale. Nevertheless, transferring their superior performance to larger-scale prototyping, i.e., air-processing via roll-to-roll compatible techniques, still […]Rodríguez-Martínez, X., Hartnagel, P., Riera-Galindo, S., Beket, G., Österberg, T., Gao, F., Kirchartz, T., Inganäs, O.
