Unlike silicon, ferroelectric crystals do not require a so-called pn junction to create the photovoltaic effect, in other words, no positively and negatively doped layers. This makes it much easier to produce solar panels.

Bhatnagar explained that pure barium titanate does not absorb much s...

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 ...
