Key Points

Performance loss in wide-bandgap perovskite solar cells is connected to halide ion migration, affecting efficiency.
Key findings suggest that mixed-halide perovskites are crucial for advancing tandem photovoltaics, specifically for their tunable bandgap.
This analysis involves investigation of mechanisms related to performance degradation in solar cells, focusing on halide ion behavior.
The implications of this research point to potential solutions and enhancements in the field of solar energy technology.

Implication

Analysis uncovers performance loss in wide-bandgap perovskite solar cells, indicating improvements for tandem photovoltaics.

Abstract

Wide-bandgap (WBG, ≥1.60 eV) mixed-halide perovskites with tunable bandgap are pivotal for advancing tandem photovoltaics (PVs). However, WBG perovskite solar cells (PSCs) suffer from severe performance loss, often linked to...
