Silicon Valley startup Ubiquitous Energy is making the world’s first transparent solar cells, a technology that could greatly expand the reach of solar power. Their technology is an invisible film that can go on any surface and generate power, which could lead to cell phones and tablets that never run out of batteries — or skyscrapers that can use their massive banks of windows as solar panels.
