  "textContent": "Perovskite solar cells are a rapidly advancing photovoltaic technology that has seen a dramatic rise in power conversion efficiency in recent years. A key driver of this progress is the use of molecular charge-selective contacts—ultrathin interlayers only a few nanometers thick—that replace conventional bulk transport materials. These molecular layers play a critical role in extracting and transporting electrical charges at the electrode interface.",
