Abstract |
Perovskite solar cells (PeSC) has undergone numerous and rapid developments leading to an unprecedented 22.7% power conversion efficiency. Discovery of a more efficient and stable hole transport material (HTM) is one of the major tasks faced in improving PeSC. Triphenylamine derivatives have been applied in various electro-optical materials and have been used as HTM in perovskite solar cell. In this presentation, we investigated a variety of heterocyclic aromatic hydrocarbon central moieties with triphenylamine substituents as possible HTM for PeSC. Energy levels, absorption spectra and electrochemical properties of the derivatives were calculated using density functional theory and time-dependent density functional theory to give the best HTM design for PeSC. |
