KIUCHI said the economic blueprint does not diminish the need to restore Japan's fiscal health.

Chen Qi, an early perovskite PV researcher, says he and his team ran hundreds of formulation optimizations over three years to improve stability and lifetime for space use. Global LEO constellations are projected to exceed 100,000 satellites over the next decade, creating substantial demand for space power. Market-standard GaAs cells cost roughly 100,000–300,000 yuan per m2; perovskite cells cost under one-tenth of that, according to Chen. Six months after founding his startup he has formed engineering and commercial teams and started building what he says is the world’s first perovskite space PV pilot line in Changping, Beijing. He expects mass production in 2027 and commercial sales to begin in 2028.
