Why aren't photo cells already manufactured to be like 90% mirrors then?

  Some guesses: - A lot more direction-dependent. - More maintenance related to keeping the right direction, maintaining more moving parts, etc. - Less convenient form factor, more susceptible to wind, more unsightly. - Less space-efficient, which matters for some applications like house rooftop installations.

    I'm not sure, but I suspect cooling requirements also enter into consideration.

    Direction dependence also means your output drops even more on cloudy/overcast days.
