페로브스카이트 태양전지의 우주분야 응용 및 전망

초록

Terrestrial solar cell technology has been dominated by crystalline silicon, offering high efficiency and long lifespan but suffering from high manufacturing costs due to energy-intensive processes. As a promising alternative, perovskite solar cells (PSCs) have gained attention for their high efficiency and low-cost fabrication. The space environment presents unique advantages for PSCs, including high solar irradiance and the absence of moisture and oxygen, which are major degradation factors on Earth. However, space also introduces extreme conditions such as radiation exposure, temperature fluctuations, and vacuum, which can significantly impact the performance and stability of PSCs. This study examines the effects of the space environment on PSCs, particularly focusing on radiation-induced degradation mechanisms and thermal stability challenges. Additionally, we explore potential strategies to enhance the radiation resistance, thermal durability, mechanical robustness, and self-healing capabilities of PSCs for long-term space applications. By addressing these key factors, we evaluate the feasibility of PSCs in space and discuss future research directions to develop more resilient and efficient solar cells for extraterrestrial missions.
