 Context examples 

On the artificial leaf, two light absorbers, similar to the molecules in plants that harvest sunlight, are combined with a catalyst made from the naturally abundant element cobalt.

In the atmospheres of hot planets like WASP-19b, it acts as a heat absorber.

(Inferno World with Titanium Skies, ESO)

The artificial photosynthetic unit inside the capsule is made up of a light absorber coated with catalysts that convert the carbon dioxide to carbon monoxide, which can be siphoned off and used as a basis for the creation of various synthetic fuels.

While studies have shown that cerebrospinal fluid, once thought to act solely as a cushioner and shock absorber for the brain, can influence the way neurons grow, Shen speculated that the large amount of fluid may itself be a symptom: We believe that extra-axial CSF is an early sign that CSF is not filtering and draining when it should.

For the handful of exoplanets with stratospheres, the absorber is typically thought to be a molecule such as titanium oxide, a close relative of titanium dioxide, used on Earth as a paint pigment and sunscreen ingredient.

As an added bonus, the researchers discovered that their light absorbers work even under the low levels of sunlight on a rainy or overcast day.

When the device is immersed in water, one light absorber uses the catalyst to produce oxygen.

These include state-of-the-art perovskite light absorbers, which provide a high photovoltage and electrical current to power the chemical reaction by which carbon dioxide is reduced to carbon monoxide, in comparison to light absorbers made from silicon or dye-sensitised materials.
