Abstract

This project aims to develop new molecularly engineered materials for perovskite solar cells (PSCs), focusing on enhanced stability and scalability. It combines synthetic chemistry, advanced material characterization, and device engineering to explore two key classes of materials: (i) conjugated diammonium cations for the fabrication of two-dimensional (2D) perovskites, and (ii) small organic molecules forming self-assembled monolayers (SAMs) for interface engineering. These materials will be integrated into PSC architectures to improve charge transport, environmental stability, and fabrication reproducibility. The Italian partner (ICCOM-CNR) will lead the molecular design and synthesis of the target organic compounds, tailoring their structure to align energy levels and optimize interaction with perovskite phases. The Brazilian partners will lead the fabrication and testing of PSCs, employing scalable techniques such as blade-coating and performing thorough stability analyses under ISOS protocols. Advanced structural, morphological, and optoelectronic characterization - including GIWAXS, PL mapping, and Cathodoluminescence - will be employed to guide the material and process optimization. By combining complementary expertise in materials synthesis and device fabrication, the project will contribute to the fundamental understanding and practical advancement of next-generation PSCs with enhanced performance and durability, accelerating their transition to commercial viability.
