The project explores the pivotal role of self-assembled monolayers (SAMs) in enhancing the performance and stability of solar cells, finally focusing on their application as hole-selective layers in perovskite and organic photovoltaic devices. Various types of SAMs, including carbazole-based, phenothiazine-based, and conjugated monolayers, will be comprehensively reviewed and further developed based on theoretical optimization and feedback from targeted microscopic and nanoscopic characterization techniques. New molecular structures, synthetic methodologies, and assembly techniques will be developed. We will exploit the structural variations in anchoring groups, linker chains, and functional head groups, examining their influence on charge distribution, energy alignment, and surface defects density. These parameters, extracted from advanced characterization and DFT calculations, will be fed into a classical semiconductor model equipped with quantum mechanical features. The model, after a validation on real fabricated devices, will unravel the role of SAMs in a photovoltaic device.
