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 × 10(11) Jones, an energy density of 1.13 × 10(4) J g(-1) and a specific capacitance of 37.5 mA h g(-1) directly charged by sunlight.
