Do photochromic goggles work in cold weather?

Yes, but with a caveat. The photochromic chemical reaction slows in cold temperatures, particularly the lightening (clearing) reaction. In temperatures below -10°C (14°F), you may notice the lens takes longer to lighten when moving from sun to shade or when clouds roll in. The darkening reaction is less affected by cold. Modern photochromic goggle technologies have improved cold-weather performance significantly compared to earlier generations, but some slowdown in extreme cold is still expected.
