Abstract

A solid-state photocapacitor is prepared, utilizing iron pyrite (FeS₂) as both the photoactive material and blocking electrode, which exhibits a high performance near-infrared (NIR) photodetectivity of 1.6 × 10¹¹ Jones, an energy density of 1.13 × 10⁴ J g⁻¹ and a specific capacitance of 37.5 mA h g⁻¹ directly charged by sunlight.
