4 FAQs about Photoinduced degradation of solar power

How does photoinduced degradation affect photovoltaic device stability?

The UPS spectra reveal that photoinduced degradation results in a mismatch of the energy levels at the perovskite/transport layer interface, which may limit the collection of charge carriers. These findings correlate well with the photovoltaic device stability under similar degradation conditions.

Does vacuum accelerate photo-induced degradation for perovskite solar cells in space?

Photo-induced degradation for perovskite solar cells in space is investigated. Vacuum accelerates the device degradation rate compared to normal pressure. Ion migration and perovskite decomposition are contributors to device efficiency loss. 1. Introduction
