After the electrolysis catalyst to help power fuel cells, now it’s the curtains: thin, cloth-like photovoltaic materials that work as solar panels in the shape of window curtains.

“These are materials which can be prepared in the chemistry lab or can be found in nature. They produce electricity when exposed to light. They are very efficient and flexible.

From a technical view, the thin-film has the potential to be produced in very high volumes, with a very low embodied energy and a low carbon footprint. These new photovoltaic materials can be produced in the same way one might print and produce a newspaper, roll to roll.”
