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. This has been revealed in a study by researchers at Martin Luther University Halle-Wittenberg (MLU). They achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which they alternately placed on top of one another. Their findings, which could significantly increase the efficiency of solar cells, were published in the journal Science Advances. Most solar cells are currently silicon based; however, their efficiency is limited. This has prompted researchers to examine new materials, such as ferroelectrics like barium titanate, a mixed oxide made of barium and titanium. "Ferroelectric means that the material has spatially separated positive and negative charges," explains physicist Dr Akash Bhatnagar from MLU's Centre for Innovation Competence SiLi-nano. "The charge separation leads to an asymmetric structure that enables electricity to be generated from light." 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 the solar panels. by Martin-Luther-Universität Halle-Wittenberg

This is a Game Changer. If you get solar, you will need to have a version of shutters for windows in case of storms. I have seen pictures of solar destroyed by hail. Also lightning. Might have to invest in lightning rods. I have seen videos of herds of sheep destroyed by lighting. And in Africa a herd of 18 elephants were killed by lightning. More hail and lightning coming during the Grand Solar Minimum. Time to put up lightning rods.
