Scientists at Martin-Luther-Universit├Ąt Halle-Wittenberg (MLU) are boosting the photovoltaic effect in ferroelectric-paraelectric superlattices. The team is reporting the photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. The researchers achieved this by creating crystalline layers of barium titanate, strontium titanate and […]
