And that sparse array of wires has exactly the same light absorption and electricity-collection properties as the conventional silicon wafer cell."

And what is going to allow for absorption or some interaction with visible light?

Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations.

However, the researchers appeared confident that these setbacks could be overcome and added that future 3D printers should permit greater control over reflectivity, light absorption and other factors allowing toy designers to incorporate additional functionality.

Here, plastics that are black to the eye actually reflect a reasonable amount of light, so it is possible to get a meaningful absorption spectrum.
