RoseStreet Labs multi-layer solar panel.
Solar panels are a great technology, yanking free energy out of the air in non-polluting way. But unfortunately, they generally only catch about 15% of the suns rays, making them painfully inefficient. Now a new kind of panel aims to bump that up.
Panels from RoseStreet Labs use three separate layers of photovoltaic cells in each panel, cranking the efficiency to more than double that of typical panels, to 35%. With each layer capturing a different part of the sun’s spectrum, the panel as a whole can deliver much more free juice to whatever its hooked up to.
One gets the feeling that, once this tech is finally perfected, solar energy will be the main source of electricity in many places. If only they could hurry the process up.
