Pathways towards 30% efficient single-junction perovskite solar cells and the role of mobile ions
Jonas Diekmann, Pietro Caprioglio, Moritz H. Futscher +13
Perovskite semiconductors have demonstrated outstanding external luminescence quantum yields, enabling high power conversion efficiencies (PCE). However, the precise conditions to…
Direct observation of state-filling at hybrid tin oxide/organic interfaces
Ulrich Hörmann, Stefan Zeiske, Soohyung Park +6
Electroluminescence (EL) spectra from hybrid charge transfer excitons at metal oxide/organic type-II heterojunctions exhibit pronounced bias-induced spectral shifts. The reasons fo…
High Open Circuit Voltages in pin-Type Perovskite Solar Cells through Strontium Addition
Pietro Caprioglio, Fengshuo Zu, Christian M. Wolff +7
The incorporation of even small amounts of strontium (Sr) into lead-based quadruple cation hybrid perovskite solar cells results in a systematic increase of the open circuit voltag…
The perovskite/transport layer interfaces dominate non-radiative recombination in efficient perovskite solar cells
Martin Stolterfoht, Pietro Caprioglio, Christian M. Wolff +12
Charge transport layers (CTLs) are key components of diffusion controlled perovskite solar cells, however, they can induce additional non-radiative recombination pathways which lim…
Stark Effect of Hybrid Charge Transfer States at Planar ZnO/Organic Interfaces
Ulrich Hörmann, Stefan Zeiske, Fortunato Piersimoni +6
We investigate the bias-dependence of the hybrid charge transfer state emission at planar heterojunctions between the metal oxide acceptor ZnO and three donor molecules. The electr…
Zinc Oxide Modified with Benzylphosphonic Acids as Transparent Electrodes in Regular and Inverted Organic Solar Cell Structures
Ilja Lange, Sina Reiter, Juliane Kniepert +6
An approach is presented to modify the WF of solution-processed sol-gel derived ZnOover an exceptionally wide range of more than 2.3 eV. This approach relies on the formation of de…
