1. A switchable window comprising:
a switchable photovoltaic (PV) device comprising a perovskite and a first side configured to transmit light; and
a static PV device comprising an active material and a second side configured to transmit light, wherein:
the switchable PV device and the static PV device each have a planar form positioned parallel to a yz-reference plane,
the first side is positioned in a first plane parallel to the yz-reference plane,
the second side is positioned in a second plane parallel to the yz-reference plane,
the first side and the second side are separated by a first gap in an x-axis direction,
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, and
the static PV device is substantially transparent to the visible spectrum of light.
