Abstract: applications increased. However, solar cells used in space have to face significant challenges. These challengesinclude exposure to high radiation, which can impact solar cell performance and Their lifespan, and brutaltemperature changes in space, which can cause damage to the cells. Furthermore, space debris, such asmicrometeoroids, can harm the cells and affect energy production. Based on previous work regarding deployingOrganic Solar Cells (OSC) and Perovskite Solar Cells (PSC) in space on a suborbital rocket [1]. This projectfocuses on the degradation of organic solar cells in the space environment. Long-termexperiments are conductedto investigate the degradation mechanisms. This involved simulating space environmental conditions on theground. Organic solar cells used in extraterrestrial conditions were mainly exposed to energetic electrons andprotons, which cause damage to the morphological and chemical structure of the organic bulk heterojunctionthrough ionization [2]. This work conducted total ionozing doses using Gamma-ray on a PBDB-T-2F:BTP-eC9system and using structural and optical characterization methods such as Grazing-Incidence Small-Angle X-rayScattering (GISAXS), Atomic Force Microscopy (AFM) and UV-Vis spectroscopy for investigating the impactof radiation on the system. These techniques showed how the structure of the organic solar cells was altered bygamma radiation. Depending on the radiation levels they were subjected to, the size domain, surface roughnessand the absorption property of the PBDB-T-2F: BTP-eC9 system changed. At the same time, a performanceanalysis was performed using a novel encapsulation method. The analysis unveiled significant potential forfuture application.
