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.

compared to pure barium titanate of a similar thickness, the current flow was up to 1,000 times stronger

This says noting of efficiency compared to standard solar panels. Seems misleading at best.

The press release is from 2021

Silence since then.

Edit: I skimmed through the study and their premise is to combine 3 crystals and break the linearity of the cristals to get a better response and better responsivity over the whole bandwidth of the light spectrum. It seems to be stable at a wide range of temperatures.

Issue is, they broke (or combined ?) the cristals with a microscopic needle but that isn't feasible for mass adoption, so they speculate that some rust process might be the best approach to try.

I'm no scientist and it's likely very false what I stated, but I think the premise is that we need to find ways to create panels with broken up cristals to give them more power.

"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.

a really good solar panel has a efficiency of 30%, idk how can you 1000x that, math doesn't add up

20,000% efficient? Cool. Mr. Boltzmann and Mr. Einstein may want to have a word, though.

I wanna ride my electric motorcycle around the country and chill out for an hour while my crazy efficient foldout panel recharges my bike.
