    Exciting news but they still have a long way to go before commercial availability:

    The big problem is that the devices are horrifically short-lived. Even the most stable device made by the first group had dropped to 80 percent of its original efficiency after just 66 hours of exposure to sunlight. The second was somewhat better, managing to reach 347 hours before dropping below 80 percent. Assuming 12 hours of sunlight a day, however, that translates to less than a month of use, which is terrible.>

      Yikes, that is bad. But like you said hopefully they can make adjustments to it and increase the longevity.
