The problem with current photocells is a) very \\\"picky\\\" about photons. Many photons are simply wasted or reflected as they do not meet the cut-off frequency. b) whilst it is theoretically possible to energize multiple electrons with a single wave packet of energy, so far it is a very complex-quantum mechanics, nuff said- with drastic reduction in max kinetic energy per electron. What the above achieved was based on a system where number of electrons divided by number of photons. Since there are much more photons with excess energy over energy required to release an electron, this is not a true efficiency. TL;DR, efficiency above is NOT Pin/Pout, and is not a true efficiency in terms of pure energy. Still, it is very impressive. Nononono…the 114% efficiency is not really 114% efficiency.

Still, it is very impressive.

Since recorded history we believe that we have "worked Out" the inner workings of the world around us and established "Laws" to explain them. We continue to compartmentalise what we don't understand and design tests to disprove them. It's not that it isn't there, we don't know how to find it.(Black Holes?... not so long ago). Lets hope it is 114%, long may new discoveries continue. NO OIL DEPANDANCY!!! Yeah Science! @freealex1 maybe we have the laws wrong.

How much it's cost? The important is where can we get these great solar cell from? How much it’s cost?

Of course it's great news for the communities. But how much the cost will be? If the new solar cells can really maximized the absorption of generating more energy than the current solar cells.

Are you saying that they've somehow managed to 'violate' the law of energy conservation (i.e. - that they are taking in 1.00 Watt of sunlight, and getting 1.14 Watts of electricity out)? That seems rather doubtful... Sorry, can you clarify what has actually been achieved?
