Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective
Advanced Science, EarlyView.This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Unveiling the Ultralow Thermal Conductivity of Hybrid Perovskites
Advanced Science, EarlyView.In hybrid perovskites, thermal energy flows through lattice vibrations of the framework (48%–65%) and organic molecules (35%–52%). When the disorder introduced by organic molecules is excluded, the temperature dependence of the vibrational thermal conductivity results from the lattice framework transits from ∼T0 to ∼T−1, and the value doubles at room ...

Mathematical Model of Bridge-Linked Photovoltaic Arrays Operating Under Irregular Conditions
TecnoLógicas, 2013 This paper presents a mathematical procedure to model a photovoltaic array (N rows and M columns) in bridge-linked configuration operating under regular and irregular conditions. The proposed procedure uses the ideal single-diode model representation for

A NUMERICAL APPROACH TO OHMIC LOSSES ASSESSMENT IN CONCENTRATING PHOTOVOLTAIC SYSTEMS [PDF]
, 2012 It is well known that concentrator solar cells operating under concentration experience a number of physical effects which affect their performances. In particular, ohmic losses can determine a noticeable performance worsening of concentrator solar cells.

Advanced Science, EarlyView.Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Advanced Science, EarlyView.A spin‐coating‐free sequential blade–dipping process is developed for efficient tin perovskite solar cells. Amorphous SnI2 templates are blade‐coated and vacuum‐dried, followed by a vertical dipping conversion. Enhanced by a synergistic additive matrix and bifunctional BATo cation, the resulting devices achieve a benchmark power conversion efficiency ...
