Continuous pin-hole free FA0.78Cs0.22Pb(I0.85Br0.15)3 flms are deposited by gas-assisted slot-die printing under ambient conditions using DMF/DMSO based ink containing Formamdinium Acetate additive. Using a binary solvent mixture of DMF and DMSO is effective in eliminating the non-perovskite phase that occurs when DMF alone is used. Print-speed, gas fow rate and chuck temperature are optimized to realize homogeneous flms with constant bandgap (1.63 eV) over large substrates (2″×4″). The perovskite flms prepared using two solvents DMF and DMF: DMSO (9:1) were incorporated in single junction devices. The resulting devices show improved fll factor with improved power conversion effciency.

Abstract We here report on the progress of the HHH Workshop, that took place in Dubrovnik in July 2023. After the discovery of a particle that complies with the properties of the Higgs boson of the Standard Model, all Standard Model (SM) parameters are in principle determined. However, in order to verify or falsify the model, the full form of the potential has to be determined. This includes the measurement of the triple and quartic scalar couplings. We here report on ongoing progress of measurements for multi-scalar final states, with an emphasis on three SM-like scalar bosons at 125$$\,\text {Ge}\hspace{-.08em}\text {V}$$ , but also mentioning other options. We discuss both experimental progress and challenges as well as theoretical studies and models that can enhance such rates with respect to the SM predictions.more » « less
