Solar cell could be cheaper than fossil fuel

I am not sure about this 114% efficiency number, it seems like gaming the system (meaning getting more than one electron per photon seems like unfair counting). However, if they can dramatically increase the overall efficiency of solar cells (the best are about 45%, but are really _really_ expensive; ‘ordinary’ ones run at 25-30%) and dramatically decrease the cost (as implied in the article) then we might be on the verge of a dramatic breakthrough (finally!). We still have to find an economical way to store the energy for use at night, quite a non-trivial thing to do, but at least we would have the incentive to develop such storage devices which is not quite at Manhattan project levels at this point.
