  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.

Ok, now we just need to know how ferroelectric crystals compare to conventional solar cells to find out what this "1000x" really means...

[hansel_der]

i would guess that they are about 1000x worse than conventional silicon

Or much worse yet, otherwise the authors could have used clear language.

Yes, it would be extremely helpful if we knew how they compared to what people are able to purchase today.
