High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

Advanced Materials, EarlyView.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

Performance Constraints of All‐Perovskite Tandem Solar Cells in Low‐Intensity, Low‐Temperature Environments

Advanced Materials, EarlyView.
All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.
