研究目的
Investigating the suitability of monolithic perovskite/CIGS and perovskite/SHJ tandem solar cells for space applications by testing their radiation hardness under high-energy proton irradiation.
研究成果
Perovskite/CIGS tandem solar cells demonstrate high radiation hardness, retaining over 85% of their initial efficiency after high-energy proton irradiation, making them suitable for space applications. In contrast, perovskite/SHJ tandem solar cells degrade significantly due to radiation-induced defects in the silicon sub-cell.
研究不足
The study focuses on proton irradiation effects and may not fully represent the complex radiation environment in space. The encapsulation and substrate materials used may also influence the results.
