Abstract Scope |
Advancing perovskite solar cell (PSC) technology requires addressing two key challenges: enhancing power conversion efficiency (PCE) through light management and improving long-term stability. This talk introduces our approach to optimizing both aspects. Effective light management is achieved using textured antireflective coating (ARC) films, which minimize reflection losses and boost light absorption. Incorporating nanoparticles and UV-converting materials into the ARCs further maximizes incident light utilization, enhancing PCE.
In the latter section, we present a poly(methyl methacrylate)-polyurethane (PMMA/PU) composite with an interpenetrating network (IPN) structure, incorporating CeO2 nanoparticles for PSC encapsulation. The IPN reduces free volume, limiting water diffusion, while CeO2 nanoparticles enhance water resistance. Encapsulated solar cells tested at 85-85 conditions demonstrate the IPN-CeO2 composite's potential for PSC encapsulation. |
