Another Japanese breakthrough.

Scientists in Japan have been discussing the possibility of using a material called perovskite for solar panels as opposed to the traditional silicon-based cells.

And now they have had their first trials and seen the results. The panels are cheaper, more lightweight, and bendable so they can go on more surfaces. 

Plus, they have a max output 1.5 times traditional silicone collar cells.
