New inverted perovskite solar cell boosts 25% efficiency, 98% stability
Researchers develop high-entropy hybrid perovskite solar cells with better efficiency and stability, promising industrial scalability.
Compared to conventional perovskites, this structure exhibits higher phase stability at high temperatures, confirmed through nuclear magnetic resonance (NMR) spectroscopy. The team constructed a perovskite solar cell using the HEHP film, which, they claim, boasts remarkable water and damp-heat resistance. “The superiority of HEHP over a single component in reducing electronic disorders could be attributed to the coexistence of multiple types of A-site cations that can synergistically interact with various defects,” the team told PV Magazine.
