A series of rigid triphenylamine (TPA) dyes have been designed with the donor (D)-π-acceptor (A) architecture. To screen the acceptor moities, we have design that’s A1 and A2. The design sensitizer to evaluate the parameters such as geometries, electronic structures, and optical properties, along with dipole moment, polarizability and first-order hyperpolarizability were calculated using density functional theory (DFT) and time-dependent DFT (TD-DFT). Photo physical properties like wavelength of maximum absorption (λmax), oscillator strength (f), light harvesting efficiency (LHE) and dipole moment ( ) have been analyzed. Based on the results A2 acceptor moities having good photo physical properties, so this A2 based dyes having good sensitizer for dye sensitized solar cells application.
