This paper presents a comprehensive analysis of international photovoltaic testing protocols, with a specific focus on the applicability of International Electrotechnical Commission and International Organic Stability Summit standards for perovskite solar cells operating in space environments. The study reveals that current testing frameworks are insufficient to replicate the extreme conditions of deep space, including high vacuum, intense ionizing radiation, and ultra-low temperatures. Experimental data from recent irradiation studies using protons and electrons, alongside temperature and irradiance profiles across planetary orbits, are reviewed to assess performance degradation and stability. The findings emphasize the urgent need for the development of standardized space-oriented testing protocols for perovskite solar cells to ensure their long-term viability in aerospace missions.
