Holographic film used with highly efficient solar cells to create “game-changing” solar panel. I have seen my share of outstanding solar innovations, such as concentrated solar setups using tiny gallium arsenide cells that achieve an astounding 42% efficiency . However, I’ve been eagerly waiting for an outstanding innovation made from more abundant materials such as silicon.
It is not unreasonable to expect that the renewable energy collected by the world’s solar panels and wind farms is being stored somewhere, ready and waiting to power our microwaves and hairdryers at a moment’s notice.
