What is it about?
All solar cells are based on electronic charges. However, electron also has a spin property that may lead to a new type of solar cell family. For that, widely available earth-abundant ferromagnetic materials like iron and nickel may be used. Solar cells using electron spin property and utilizing iron and nickel like metals may be extremely cheap and recyclable.

Why is it important?
This paper show the realization of the electronic spin-based solar cell effect. This solar cell effect was observed on a magnetic tunnel junction based molecular spintronics device that mainly employed NiFe alloy. If large scale solar cells are produced using this approach, a new family of solar cells will evolve.
