    Just quoting the article:

    “from around 6% to over 27%, close to the limits of what single-layer photovoltaics can achieve today.”

    But I guess it depends too on how many layers we’re talking about which isn’t specified.

      You’re misrepresenting what they say:

      During just five years of experimenting with our stacking or multi-junction approach, we have raised power conversion efficiency from around 6% to over 27%, close to the limits of what single-layer photovoltaics can achieve today.

      We believe that, over time, this approach could enable the photovoltaic devices to achieve far greater efficiencies, exceeding 45%.

      “6% to over 27%” isn’t the range of what they can achieve now. 6% efficiency was where the technology was at 5 years ago, and now they get 27%.
