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.
