Japan Quit Paying for Solar Panels. What It's Building Instead Rolls Up Like Paper

Japan just cut conventional silicon solar panels out of its new subsidy programs from fiscal 2027 — deliberately disqualifying the technology that holds roughly 95% of the global market. In its place: a perovskite solar film thin enough to roll up, light enough for roofs that can't carry glass, and in some versions transparent enough to sit inside a window. This video breaks down why one of the world's most advanced industrial nations is betting against the winner. Why Japan's solar ceiling is geological rather than financial. How a chemist who spent two decades coating light-sensitive film at Fuji Photo Film invented this material in a Yokohama lab in 2009 at 3.8% efficiency. Why Sekisui Chemical is installing its 100 MW line inside a factory it bought from Sharp. And why the single most important ingredient in the whole story is iodine pumped from ancient brine under Chiba prefecture. We also cover the uncomfortable side: the lead inside the cells, the 15% efficiency, the ten-year rated life, the Chinese gigawatt lines that opened two years ahead of Japan's, and the analysts who think the targets need rethinking.
