EROI on organic solar

(Apologies if this is not quite the correct category, I couldn't really find any single category in which to discuss this. The primary query is at least a matter of engineering more than anything else.)

Does anyone know of any figures for the energy return on invested of the nascent organic PV technology?

Or perhaps know of anywhere I could find figures with which to calculate this.

I'm given to understand that the state of the art has rather fantastic payback time (measured in months rather than years), but rather short total lifetime.

With this being the case I guess one would have to consider transportation/mounting/wiring/installation/etc costs in addition to the panel.

Another important factor is the very small initial investment required for organic PV.

This thought came up upon reading Tom Murphy's blog, specifically this. This got me thinking along the lines of solar potentially surpassing other infrastructure in terms of EROI.

Subsidies and other government incentives aside (from my reading, there are arguments that both solar and the oil/coal industry have more subsidies than the other in various places), would we see a sudden shift towards solar if it were to achieve a better EROI than oil/coal plants+fuel?

Are there other factors that would prevent this?

Some that come to mind would be:

Cost of land -- parking lots and roofs come to mind.

Distribution -- The sunniest areas are not always where you want power. Especially in winter

Everything else that goes with non base-load power
