Abstract
The present disclosure relates to a device that includes a switchable photovoltaic (PV) device that includes a first active material and a static PV device that includes a second active material, where the switchable PV device and the static PV device are positioned substantially parallel to one another, the switchable PV device has a first state that is substantially transparent to a first wavelength of light in the visible spectrum, the switchable PV device has a second state this is substantially opaque to a second wavelength of light in the visible spectrum, the switchable PV device can be reversibly switched between the first state and the second state, the static PV device is substantially transparent to the visible spectrum of light, and both the switchable PV device and static PV device are capable of generating power.
