The exploration of the outer solar system so far relied heavily on the use of scarce, highly radioactive plutonium stockpiles for power generation, as traditional solar cells have a too low power-to-mass ratio in low light environments to be suitable for those missions. Latest advances in organic and perovskite solar cells now open up the possibility of utilizing them on lightweight foils as photovoltaic solar sails for efficient power generation in low solar irradiation conditions.
We report the deployment of various organic and hybrid solar cell systems on a sounding rocket and their operation in outer space. We investigate the environmental influences during ascent, exposure to space, and reentry on the photovoltaic performance. We further study and compare the changes in morphology and optoelectronic behavior at various stages during the space mission, isolating different external impact factors.
