Abstract

Present study deals with photovoltaic and electronic properties for new organic
dyes sensitizers for solar cells applications. B3LYP-DFT method was used for the
calculations of ground state and the TD-DFT method was used for the excitation
properties of the structures under study. Mentioned calculations were done by
performing the Gaussian 09 package. Our results showed that HOMO and LUMO
differed slightly, suggesting that different structures play an important role in
electronic material goods and improving their ability to accept electrons. The of open
circuit voltage with the energy gap are the parameters that they manipulate to improve
the value of solar cell devices. Furthermore, the results show that these compounds
can be used as organic sensitizers for solar cells according to the probability of the
electron injection process of the compounds in the TiO2 conduction band.
