Generating Light from Darkness: Joule
Using narrowband emitters to emit heat through the atmospheric IR window, you can make a plate cold on the sky facing side, creating a heat difference a thermoelectric generator can utilize

Window film could even out the indoor temperature using solar energy | Chalmers
Neat trick is it's yellow when the sun isn't shining, but clears up when it is shining, then goes yellow again while reradiating stored heat

A radiative cooling structural material | Science
using boiling hydrogen peroxide, these researchers reduced/compressed wood by removing the lignin, making an engineered wood with interesting properties, such as high strength. The kicker is that the white material is also a narrowband IR emitter tuned to dump heat to space through the atmospheric windows, so it can cool you in broad daylight.

Broadband Light Management with Thermochromic Hydrogel Microparticles for Smart Windows: Joule
Using 500nm thermochromic nanoparticles to turn glass frosty at 85F, and reject outside IR heat. So if it gets warm, a window can turn transluscent to stop solar heating.

OSA | Evaluation of 3D printed optofluidic smart glass prototypes
So if you fill a plastic clear retroreflector with the same index of refraction liquid, the whole thing becomes clear instead of operating as a retroreflector, effectively becoming variable transparency smartglass

Radiative cooling to deep sub-freezing temperatures through a 24-h day–night cyc...
New record, but requires shading from direct sunlight, and a vacuum chamber, and a zinc selenide emission window on the vacuum chamber wall. But 37 degrees below atmospheric ambient is pretty damn good.

Pythagoras Solar: HomePage
Using double pane window optical tricks and a somewhat thicker window panel, this company claims to hold off IR while generating solar power through a venetian blind solar PV array embedded in thicker double pane glass windows, for vertical solar array integration into building facades. Not a bad idea...

RavenBrick, LLC
A window material technology that darkens when the window gets hot (so it reduces sunlight during the summer but stays transparent in the winter.) So the trick here is not a gradient tint effect, but a sudden window darkening when you hit a critical temperature. They are using this as building insulation as well, to help reject heat in the summer but draw it in when it's cooler outside.
