Inexpensive solar cells were created from rust and water

In the Nature Photonics magazine appeared an article of a group of chemists from the Federal Polytechnic School in LaUSAnne, Switzerland, under the direction of Kevin Sivula, that were created by solar cells from rust (Fe2O3) and water with record efficiency, which allow to save up to 16% of the energy of Sunlight. According to Kevin Sivula, a square meter of new solar panels cost only $ 80, this is mainly the cost of glass plates, on which are located the components of the solar cells...
