Anyone know of any solar cell vendors that sell
solar cell modules that put out 6-9volt @ 100mA?

I think Harbor Freight had something.
Lots of stuff from places like Electronic Goldmine,
and others, real cheap.

JC Whitney sells 12 volt panels competitively. These are not as
efficient when loaded to 6-9 volts, but they put out at least as much
current as when run with a 12 volt load.

Another option might be to use a different voltage panel,
whatever has a good price, and then use a small switcher to run
the cells at their optimum load.

Seems foolhardy to me, to use a boost circuit, and waste a lot of power.
Just put more PV cells in series to increase the voltage.
