Solar cells currently in use are mostly silicon-based, but their efficiency is limited. This has led researchers to explore new materials.

Researchers at Martin Luther University Halle-Wittenberg (MLU) have discovered a new method to increase the efficiency of solar cells by a factor of 1,000. The team of scientists achieved this breakthrough by creating crystalline layers of barium titanate, strontium titanate, and calcium titanate, which were alternately placed on top of one another in a lattice structure.

    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.
