Ionic polarization-induced current–voltage hysteresis in CH3NH3PbX3 perovskite solar cells

Nature Communications, 2016
The origin of hysteresis remains an open question in lead-halide perovskite solar cells. Here, Meloni et al. investigate the causes of hysteresis using an experimental and computational approach, finding that the observed hysteresis is due to halide ion ...

Photophysics of Lead-Halide Perovskite

, 2018
The Sun provides Earth with a greenhouse gas free source of energy that exceeds the annual energy consumption by orders of magnitude. Current solar cell technology limits the percentage of harvested solar energy that can be used to generate electricity; this is why new concepts and materials for photovoltaics are being explored.

Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

Advanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

An Examination of the Cs2NaInCl6 Luminescence: Interplay of Self‐Generated In+ and Doped Sb3+, Er3+/Yb3+ Ions

Advanced Optical Materials, EarlyView.
A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.
