But that is limited to about 30% efficiency, since you are limited by the Carnot limit (T[h]-T[l])/T[l], with all T's in Kelvin. You are limited by how high a temperature you can get your illuminated surface too, which is not all that high. So about 30% is the best. But that 'best' is not good enough. Solar thermal?

Silly-cone (intended) solar sales er cells is the focus of the subsidised (from oil) companies. There is a reason why the silicon cell has been so inefficient for so long. There was no real demand and no need. Now we have a need. Solar thermal is another way to go - direct heat (from the sun) converted to electricity.

Or is it still too soon to know which conjugated polymer technology will replace it?
