Journal Article
Alam, S., Aldosari, H., Petoukhoff, C. E., Váry, T., Althobaiti, W., Alqurashi, M., …Laquai, F. (2024). Thermally-Induced Degradation in PM6:Y6-Based Bulk Heterojunction Organic Solar Cells. Advanced Functional Materials, 34(6), Article 2308076. https://doi.org/10.1002/adfm.202308076

Thermally induced degradation of organic photovoltaic devices hinders the commercialization of this emerging PV technology. Thus, a precise understanding of the origin of thermal device instability, as well as identifying strategies to circumvent deg...

28.2%-efficient, outdoor-stable perovskite/silicon tandem solar cell (2021)
Journal Article
Liu, J., Aydin, E., Yin, J., De Bastiani, M., Isikgor, F. H., Rehman, A. U., …De Wolf, S. (2021). 28.2%-efficient, outdoor-stable perovskite/silicon tandem solar cell. Joule, 5(12), 3169-3186. https://doi.org/10.1016/j.joule.2021.11.003

Stacking perovskite solar cells onto crystalline silicon bottom cells in a monolithic tandem configuration enables power-conversion efficiencies (PCEs) well above those of their single-junction counterparts. However, state-of-the-art wide-band-gap pe... Read More about 28.2%-efficient, outdoor-stable perovskite/silicon tandem solar cell.

Charge Carrier Recombination at Perovskite/Hole Transport Layer Interfaces Monitored by Time-Resolved Spectroscopy (2021)
Journal Article
Khan, J. I., Isikgor, F. H., Ugur, E., Raja, W., Harrison, G. T., Yengel, E., …Laquai, F. (2021). Charge Carrier Recombination at Perovskite/Hole Transport Layer Interfaces Monitored by Time-Resolved Spectroscopy. ACS Energy Letters, 6(12), 4155-4164. https://doi.org/10.1021/acsenergylett.1c01931

Carrier recombination at the interface between charge extraction layers and the perovskite photoactive layer in solar cells reduces the quasi-Fermi level splitting (QFLS) and hence the device's open-circuit voltage (VOC). Distinguishing between inter... Read More about Charge Carrier Recombination at Perovskite/Hole Transport Layer Interfaces Monitored by Time-Resolved Spectroscopy.

Intrinsic efficiency limits in low-bandgap non-fullerene acceptor organic solar cells (2020)
Journal Article
Karuthedath, S., Gorenflot, J., Firdaus, Y., Chaturvedi, N., De Castro, C. S., Harrison, G. T., …Laquai, F. (2021). Intrinsic efficiency limits in low-bandgap non-fullerene acceptor organic solar cells. Nature Materials, 20(3), 378-384. https://doi.org/10.1038/s41563-020-00835-x

In bulk heterojunction (BHJ) organic solar cells (OSCs) both the electron affinity (EA) and ionization energy (IE) offsets at the donor–acceptor interface should equally control exciton dissociation. Here, we demonstrate that in low-bandgap non-fulle... Read More about Intrinsic efficiency limits in low-bandgap non-fullerene acceptor organic solar cells.
