A model photosensitizer (D5) for application in dye-sensitized solar cells has been studied by a combination of XRD, theoretical calculations, and spectroscopic/chemometric methods. The conformational stability and flexibility of D5 and molecular interactions between adjacent molecules were characterized to obtain the driving forces that govern D5 uptake and grafting and to infer the most likely arrangement of the molecules on the surface of TiO2. A spectroscopic/chemometric approach was then used to yield information about the correlations between three variables that govern the uptake itself: D5 concentration, dispersant (chenodeoxycholic acid; CDCA) concentration, and contact time. The obtained regression model shows that large uptakes can be obtained at high D5 concentrations in the presence of CDCA with a long contact time, or in absence of CDCA if the contact time is short, which suggests how dye uptake and photovoltaic device preparation can be optimized.

The present invention provides an organic dye having heteroleptic electron acceptors which are represented by chemical formula 1. The organic dye having the heteroleptic electron acceptors according to the present invention uses heteroleptic electron donors to use light absorbed energy as an energy antenna for transferring dye particles, and uses the heteroleptic electron acceptors to increase the number of LUMO participating a light absorbing mechanism and to evenly absorb wavelengths in the entire range of visible light, thereby having excellent photoelectricity.COPYRIGHT KIPO 2017
