Oh, I just noticed the CRC table is located on page 14-10, not 18-10
as I noted. If you look at solar insolation factors by frequency you
see it drops off to nothing at the tails. For example, from 0 to 120
nm there is only 0.00044 percent. From 120 to 140 there is only
another .00009 percent. The table actually shows that from 0 to
100,000 nm the cumulative percent of solar insolation is 99.999002
percent. So basically we are quibbling about a few thousandths of a
percent. Below is an updated table using your range.
Percent solar constant at aircraft altitude:
Lambda (nm) Cum % % Range
0 - 10 *** less than 0.00044 percent***
10 - 400 8.725 8.725 UV
400 - 700 46.879 38.154 Visible
700 - 100000 99.999 53.120 IR
100000 - 1000000 *** less than .000998 percent ***
Derived from page 14-10 of the 74th Edition of The CRC Handbook.
The original article seems to leave out about 54 percent, which is
not even close.
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.

According to my table
(http://hyperphysics.phy-astr.gsu.edu/hbase/ems1.html)
UV is only considered to be wavelengths between 10nm
and 400nm, and IR is wavelengths from 750nm to 1mm
(1,000,000nm)
So, your table does not include x- and gamma- rays,
nor the RF frequencies.

Doesn't have to total to 100%
IR, Visible, and UV do not cover the entire EM
spectrum, the sun puts out energy over a very
broad
range of frequencies.
Sure it does. Look at the table again.
Percent solar constant at aircraft altitude:
Lambda (nm) Cum % % Range
0 - 400 8.725 8.725 UV
400 - 700 46.879 38.154 Visible
700 - 100000 99.999 53.120 IR
