INTEGRATED PHOTOVOLTAIC-BATTERY DEVICE AND RELATED METHODS

摘要

Provided are FeS2 based photovoltaic battery devices comprising a transparent substrate, an active layer disposed over the transparent substrate, the active layer comprising a porous film of FeS2 nanocrystals and a halide ionic liquid infiltrating the porous film, and an electrode disposed over the active layer. The device may be configured such that under exposure to light, photons incident on the active layer are absorbed by the FeS2 nanocrystals, generating a current and a voltage, whereby a separation of charge within the active layer is created, which is discharged in the absence of the light.

1. A photovoltaic battery device comprising:
a transparent substrate; an active layer disposed over the transparent substrate, the active layer comprising a porous film of FeS2 nanocrystals and a halide ionic liquid infiltrating the porous film; and an electrode disposed over the active layer, wherein the device is configured such that under exposure to sunlight, photons incident on the active layer are absorbed by the FeS2 nanocrystals, generating a current and a voltage, whereby a separation of charge within the active layer is created, which is discharged in the absence of the sunlight.
