there's very little data in the article-it's important to know what bandwidth this responds to-visible spectrum, microwave, infrared.
Essentially, a photodiode, or photocell, is just a diode that changes it's junction when exposed to the frequency it's doped to respond to. If their
design is a wideband device, perhaps it has a better destiny-a solar cell that is more efficient and sensitive to a much wider band of radiation. Even
a modest improvement in solar cell efficiency makes a solar power infrastructure add-on immensely mroe feasable and profitable enough to get the
attention of the greediest politicians.
A much better goal than the whole "let's call it a sensor and market it as a security device to milk DHS funds" business plan that would simply
place the patents under government/military control.
