To get the 1000x figure, the research is comparing photocurrents from bulk BTO and their special crystal-aligned BTO at a specific wavelength of incident light (306nm).
They also compare photocurrents under a solar simulator and achieve 100x increase vs bulk BTO.
At no point do they make comparison to state of the art BTO cells, which almost certainly aren't just bulk BTO but are likely doped, nanostructured, or have some other novelty.
- wishawa 5y agoThat is true. The research is good. But the headline, the article itself, and especially this comment by the author > Our apologies for not making this clear. The photovoltaic effect was increased by 1000 times compared to previous output achieved from cells made of ferroelectric crystals, not from prevailing solar cells made of silicon or other conventional materials. misleadingly make it seem like they made 1000x progress from the current best.
