ABSTRACT
Abstract:
The search for efficient energy materials remains critical to addressing climate change and the rising global energy demand. Among emerging photovoltaic technologies, perovskite solar cells (PSCs) have gained considerable attention due to their high efficiency and low fabrication costs, positioning them as a strong candidate to complement or surpass conventional silicon solar cells. This research work focuses on overcoming key challenges in developing stable and efficient PSCs under ambient-air conditions, a necessary step toward scalable and industrially viable production. It presents a comprehensive approach that combines robust ambient fabrication protocols, surface passivation of the perovskite film, and the fabrication of all-scalable PSCs, enabled by modifications to the electron transport layer, i.e., SnO2. By addressing both extrinsic (e.g., moisture, oxygen) and intrinsic (e.g., grain boundary defects, interface instabilities) factors, the work demonstrates significant advancements, including achieving 24.5% efficiency in fully ambient-fabricated devices with excellent operational stability. This work bridges the gap between lab-scale research and large-scale manufacturing of PSCs.
