Progress in Flexible Perovskite Solar Cells: Paving the Way for Scalable Manufacturing

Advanced Materials Technologies, EarlyView.
Perovskite solar cells (PSCs) are well positioned for a successful market uptake. This is due to an unprecedented improvement of their efficiency and stability since the first report in 2009. In this review paper, the building blocks for the scalable manufacturing and future commercialization of flexible PSCs and their pathway to impact will be ...

Surfing the Color Map with Carbazole‐Appended Cyclometalated N‐Heterocyclic Carbene Pt Complexes and Their Application in Green Organic Light‐Emitting Devices

Advanced Optical Materials, EarlyView.
Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837
