Think about it, Alberto. IF they can make these solar cells for about the same cost as present solar cells, then by tripling the efficiency they drastically improve the economic viability (it creates 3 times the energy!). Time will tell whether the IF is possible. -- Erik Reuter http://www.erikreuter.net/
