We are presently looking for a material that will be used to
attach solar cells to an aluminum substrate. Cell efficiency
decreases as the cell temperature increases. Films such as
Tefsel and Tedlar are commonly used. These exibit good electrical
insolation, but low thermal conductivities.

any recommendations would be greatly appreciated.

  How about passivating your aluminum panel surface with thin film
diamond?  Thermal conductivity near room temperature is five times
that of copper, and it's a very good insulator.

  Barring that, a diamond filled epoxy would probably do the trick.
They use industrial diamond (abrasive grade) so the cost isn't too
outrageous.
