Glazing with heat flux sensor and/or methods of making the same

A switchable window glazing assembly, comprising:

• a switchable window including a first glass substrate and a second glass substrate;
• a radiation shield covering, directly or indirectly, at least a part of a peripheral edge area of the first glass substrate;
• and
• a dual junction solid-state heat flux sensor, comprising:
• a first junction oriented in the assembly at a first location at which radiation from a radiation source is receivable through the first glass substrate,
• a second junction oriented in the assembly at a second location that is blocked from the radiation source by the radiation shield, and
• circuitry configured to generate a signal based on a differential between transduced voltages respectively generated at the first and second junctions, so that the assembly is configured to adjust transmission of the switchable window based on the signal that is based on the differential by adjusting voltage applied to a liquid crystal layer provided between the first and second glass substrates.
