Article Synopsis
- Perovskite solar cells (PSCs) show promise for space photovoltaic technology due to their high efficiency and good radiation tolerance, but they need to resist atomic oxygen (AtOx) degradation for successful use in space.
- Exposure to AtOx for 2 hours reduced the efficiency of PSCs significantly, with non-encapsulated devices losing up to 43% of their power conversion efficiency (PCE), whereas those with a silicon oxide (SiO) barrier retained over 97%.
- Research indicates that degradation in passivated PSCs, which use phenethylammonium iodide (PEAI), is mainly due to inefficient charge extraction and the rapid degradation of the PEAI interlayer,
