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.

Relevance of Long Diffusion Lengths for Efficient Halide Perovskite Solar Cells
Akel, S.; Kulkarni, A.; Rau, U.; Kirchartz, T. PRX Energy 2023, 2, 013004 Diffusion lengths are abundantly mentioned as a key enabler of high performance in lead-halide perovskite solar cells based on the implicit assumption that diffusion lengths are directly connected to efficient collection of charge carriers. While long diffusion lengths are indeed an important […]

Comparing Methods of Characterizing Energetic Disorder in Organic Solar Cells
Hartnagel, P., Ravishankar, S., Klingebiel, B., Thimm, O., Kirchartz, T. Adv. Energy Mater. 2023, 13, 2300329 The energetic disorder has been known for decades to limit the performance of structurally disordered semiconductors such as amorphous silicon and organic semiconductors. However, in the past years, high-performance organic solar cells have emerged showing a continuously reduced amount […]Hartnagel, P., Ravishankar, S., Klingebiel, B., Thimm, O., Kirchartz, T. Adv.

Understanding the Thickness and Light-Intensity Dependent Performance of Green-Solvent Processed Organic Solar Cells
Lübke, D.; Hartnagel, P.; Hülsbeck, M.; Kirchartz, T. ACS Materials Au 2023, 3, 215 For indoor light harvesting, the adjustable band gap of molecular semiconductors is a significant advantage relative to many inorganic photovoltaic technologies. However, several challenges have to be overcome that include processability in nonhalogenated solvents, sufficiently high thicknesses (>250 nm) and high […]Lübke, D.; Hartnagel, P.; Hülsbeck, M.; Kirchartz, T.

Enhancing Built-in Electric Fields for Efficient Photocatalytic Hydrogen Evolution by Encapsulating C60 Fullerene into Zirconium-Based Metal-Organic Frameworks
Liu, L., Meng, H., Chai, Y., Chen, X., Xu, J., Liu, X., Liu, W., Guldi, D. M., Zhu, Y., Angew. Chem. Int. Ed. 2023, 62, e202217897. https://doi.org/10.1002/anie.202217897 High-efficiency photocatalysts based on metal-organic frameworks (MOFs) are often limited by poor charge separation and slow charge-transfer kinetics. Herein, a novel MOF photocatalyst is successfully constructed by encapsulating […]Liu, L., Meng, H., Chai, Y., Chen, X., Xu, J., Liu, X., Liu, W., Guldi, D. M., Zhu, Y., Angew. Chem. Int.
