Synthesis and evaluation of simple molecules for dye sensitized solar cells
Source abstract
Abstract
Abstract Four metal-free organic dyes comprising an arylamine-based D-π-A construction was designed at the molecular level and synthesized for use in dye-sensitized solar cells (DSSCs). The absorption spectra, electrochemical and photovoltaic properties of these dyes were extensively investigated. The results revealed that the absorption characteristics of all the newly prepared dyes were strongly shifted with an end-absorption far into the near infrared region due to the introduction of different chromophore groups, and the LUMO levels of the dyes were also modulated to some different extent. Otherwise, it was found that D2 showed an overall conversion efficiency of 2.61% reaching 86% with respect to that of an N719-based device fabricated under similar conditions. The origin of this correlation and its implications in materials design and device performance are discussed.
