That article - and especially the title - seem misleading. To quote (emphasis mine):

The result surprised even the research group: compared to pure barium titanate of a similar thickness, the current flow was up to 1,000 times stronger, despite the fact that the proportion of barium titanate as the main photoelectric component was reduced by almost two thirds.

I am sure this is exciting and very important research though.

"The result surprised even the research group: compared to pure barium titanate of a similar thickness, the current flow was up to 1,000 times stronger..."

so this offers the possibility of barium titanate PV cells that may be marginally more efficient and less expensive than existing silicon PV cells.

seems to be another "in a few years" tech that, while welcome, probably does not deserve the clickbait headline.

"The result surprised even the research group: compared to pure barium titanate of a similar thickness, the current flow was up to 1,000 times stronger, despite the fact that the proportion of barium titanate as the main photoelectric component was reduced by almost two thirds."... So not actually 1000x better than current technology, just 1000x compared to pure barium titanite. Garbage clickbait, but "clever technique applied to ineffective solar cell technology scrapes 1% efficiency when used in UV spectrum" does not have the same appeal.
