Austrian scientists create a cheap, flexible solar cell just 3 micrometers thick

has been something of a holy grail in solar cell development; the mineral is abundant, cheap, lightweight, and highly efficient when it comes to absorbing light. It does, however, have one major downside: perovskite is water-soluble. In experiments to utilize the mineral, this has meant solar cells have either been light and degradable or heavier and less efficient. But an effort by researchers at Johannes Kepler University Linz in Austria has created a relatively stable solar cell that is just three micrometers thick and yields 12 percent efficiency.
