#STAPOS - Stability of perovskite and organic solar cells

Description of topical focus

The stability of novel solar cells based on perovskite or organic semiconductors has been one of the major challenges in further development of thin film photovoltaics. Perovskite solar cells have achieved a world record efficiency of single-junction solar cells reaching 25.5% and the tandem devices reaching 29.8%. Organic solar cells have achieved more than 18% device efficiency. In view of the device stability, many great achievements have been made in the past couple of years.

The lifetime characterized as T80 has significantly extended to over 10,000 hours for encapsulated photovoltaic devices from both, organic and perovskite semiconductors. Novel understanding and strategies for enhancing the device stability have been reported in the recent literature. Thus, it is necessary and timely to hold a symposium on the stability of organic and perovskite solar cells to collect the most important progress and insights into these related fields.

For perovskite solar cells, topics include progress made in device stability by immobilizing ion migration, minimizing surface defects in charge selective contacts, by energetic level alignment modification, by stabilizing the phase structure of perovskite film, etc.

For organic solar cells, stability of the blend microstructure, the electronic processes in the solar cell, a potential advantage of single-component solar cells, and stability of large-scale processed solar cells are among the topics in this symposium.
