Researchers at Martin Luther University Halle-Wittenberg achieved an increase in the photovoltaic effect of ferroelectric crystals by a factor of 10 by creating crystalline layers of barium titanate, strontium titanate and calcium titanate, which they alternately placed on top of one another.
Their findings, which were published in the journal Science Advances, could significantly increase the efficiency of solar cells.

In their paper, the researchers explained that most solar cells are currently silicon-based, which means that their efficiency is limited. This is what prompted them to examine the properties of barium titanate, a mixed oxide made of barium and titanium.
“Ferroelectric means that the material has spatially separated positive and negative charges,” Akash Bhatnagar, co-author of the study, said in a media statement. “The charge separation leads to an asymmetric structure that enables electricity to be generated from light.”
Recent discovery may give solar cells 1,000% more power
