Perovskite solar cells are expected as next-generation photovoltaics due to their high efficiency, light weight, and low cost, but durability remains a challenge. In this study, we introduced a novel heteroaryl derivative into the hole transport material to suppress degradation under high temperatures. We comprehensively report the durability improvement effects, including outdoor testing.
