Bulk Heterojunction Solar Cells: Porphyrins, Dpps and Bodipys As Building Blocks for Efficient Donor Materials

Abstract

Among the different types of organic semiconducting materials, porphyrins, DPPs and BODIPYs based small molecules and conjugated polymers have attracted high interest as efficient semiconducting organic materials for dye sensitized solar cells (DSSC) and bulk heterojunction (BHJ) organic solar cells. Interestingly, they offer a synergistic effect when used together within a material, this coming from high complementarities of their absorption spectra, adapted prerequisites in order to be efficient energy transfer partners, and suitable frontier orbitals energy levels. We have recently designed different porphyrins, DPPs and BODIPYs based electron donor small molecules/polymers for bulk heterojunction organic solar cells (Figure), and now report their synthesis as well as the study of their electrochemical, photophysical and photovoltaic properties.The “Consulat Général de France à Québec” and the “Programme Samuel de Champlain 2015/2016” are acknowledged for funding.
