The original article seems to leave out about 54 percent, which is
not even close.
The above was supposed to say 45 percent.
Here is the quote again:
One challenge for organic solar cells has been the efficient
capture and conversion of sunlight. Sunlight is comprised of
photons (particles of light) that are delivered across a spectrum
that includes invisible ultraviolet (UV) light, the visible
spectrum of colors -- violet, indigo, blue, green, yellow, orange
and red -- and the invisible IR spectrum. The amount of incoming
photons across the UV, visible and IR spectrums is about 4, 5 and
45 percent, respectively.
