Abstract
Crystalline silicon solar cells modules have attracted increasing interests for the booming commercial low and middle orbit constellations. In this paper, silicon heterojunction (SHJ) solar cell modules/arrays with lightweight flexible packaging material are prepared on rollable flexible thin p-type SHJ solar cells. The modules are prepared using traditional module-integrated lamination processes to reduce costs. The SHJ solar cell modules exhibit a rolling manner, the least critical bending radius is less than 5 cm, which enables Roll-Out Solar Arrays (ROSA), due to the edge smoothing technology of solar cells and lightweight flexible encapsulation materials. The conversion efficiency of soalr cell moduloes is over 21% at AM0 illumination. The specially designed stress-relief structure allows the arrays to operate stably 1000 times under ±100℃ temperature shocks. The ultraviolet and atomic oxygen resistance of SHJ solar cell modules is characterized.
