dc.description.abstractSolar cells are limited in their efficiency by the "single junction limit," where photons with energies above the bandgap lose their energy due to thermalization. "Singlet exciton fission" is the process of splitting a high-energy molecular excitation ("singlet exciton") into a pair of low energy ones ("triplet excitons"). As a result of this approach, solar cells seem to be able to generate two electrons per photon, hence exceeding the singlet junction efficiency limit [1]. 2D layered perovskites are emerging as an alternative to 3D analogs that could overcome stability issues in perovskite solar cells (PSCs). There are, however, weak interactions among layers in 2D Ruddlesden-Popper (RP) phase perovskites with monoammonium cations, potentially destabilizing the layered perovskite structure and degrading its performance [2]. In this thesis, our research focuses on creating new materials for singlet-fission-based 2D Ruddlesden-Popper (RP) phase layered perovskites solar cells that could generate two electrons per photon and removing the van der Waals gaps to achieve higher structural stability for PSCs which might enhance Power Conversion Efficiency (PCE) of solar cells.en_US
