Synthesis And Characterization Of A Novel Donor Polymer Derivatives For Opv
OPVs based on the bulk heterojunction(BHJ) solar cell composed of electron withdrawing fullerene derivatives and electron donating polymers have attracted outstanding attention over the last two dec-ades years. This is the motivation for the development of organic photovoltaic (OPV) devices and mate-rials, which are exhibited advantages such as low cost of fabrication using roll to roll printing techniques for light weight devices, flexibility and abundant availability. Notable progress has been made in improving the power-conversion efficiency of organic photovol-taics as single BHJ have surpassed 9% and the power-conversion efficiency of tandem OPV has smashed 11%. Despite these high-efficiency solar cells, many researcher have focused on the donor material design to efficient OPVs. In this paper, we report the synthesis and characterization of a novel derivatives for OPV. The proposed polymer exhibits good solubility, sufficient thermal stability, moderate UV-vis ab-sorption wavelength and energy levels. Our results reveal that the copolymer with donor-donor composi-tion is a viable candidate as a semiconductor in OPVs, and it is possible to further improve solar cells.
