La Rivista del Nuovo Cimento Hybrid perovskites for photovoltaics: Story, challenges and opportunities
A. Alberti, E. Smecca, S. Sanzaro, G. Mannino, I. Deretzis, A. La Magna
Photovoltaic technologies based on hybrid perovskites have been a breakthrough in the field, competing with the consolidated silicon counterparts. The progress of the electrical performance has indeed created high expectation in the market uptake. On the other hand, their low structural stability, primary of the MAPbI3, risks to severely retard their dissemination. The review describes the path from the early stage to the recent development of photoactive hybrid perovskites, highlighting limits and strengths. The focus is primarily on structural aspects and optical response of the material under conditions that mimic its operation, to enlighten the origin of the limited perovskite durability. Protocols are provided for predictive or comparative evaluation of the attitude of materials to defect formation. These protocols can be also applied to validate novel stabilisation strategies. All in all, these features frame the exceptionality of hybrid perovskites in their crystal-liquid duality.

EPJ E – Topical Review
Liquid-liquid criticality in the dielectric constant and refractive index: A perspective
P. Losada-Pérez
The critical region in the phase diagram of condensed matter systems such as fluids or fluid mixtures is characterized by the anomalous behaviour of specific thermodynamic properties. In a new review article published in EPJE, Patricia Losada-Pérez describes recent progress in the understanding of the behaviour of two intimately related properties, the dielectric constant ε and the refractive index n, when approaching the liquid-liquid critical point in binary liquid mixtures.
