Natural dyes extracted from Ligustrum vulgare, Juniperus sabina, and Papaver rhoeas for novel DSSC applications

Abstract

An effective extraction strategy has been devised to get natural dye sensitizers from Ligustrum vulgare fruit (M1), Juniperus sabina fruit (M6), and Papaver rhoeas petal (M9) to produce dye-sensitized solar cells (DSSCs). The power conversion efficiencies (PCE) achieved from the DSSCs with dyes extracted from Ligustrum vulgare fruit, Juniperus sabina fruit, and Papaver rhoeas petal are 0.48 %, 0.55 %, and 0.42 %, respectively. The improved photovoltaic efficiency of the DSSCs created using Juniperus sabina fruit can be primarily due to the notable increase in the open circuit voltage, which reached 0.66 V.
