The new fully transparent solar cells allow visible light through but the light on the invisible end of the spectrum is being selectively collected and used for electricity. The technology instead of creating smaller and smaller components to hide them in the panels developed an invisible film or coating to be applied over existing materials that concentrates the solar energy.

Existing panels have about a 22% efficient and absorb all frequencies of light whereas new transparent solar cell technology only absorbs the invisible light spectrum with the visible light passing through and has an efficiency today of about 10%. This is a definite drop but it is expected to reach 20%. The thing to keep in mind is that it’s more about surface area so try to imagine a skyscraper being made entirely from these solar concentrater panels. They could power it.
