Effect of Solvent Annealing for Efficient Polymer Solar Cells

Article Preview

Abstract:

In this paper, we investigate an active layer treatment method that is referred to as solvent annealing. Organic solar cell was fabricated and an isopropanol (IPA) solvent annealing process was carried out. The experiment result should that the value of absorbance and the crystallinity is improved by isopropanol solvent annealing of active layer. Moreover, the current density, series resistance and the efficiency improved, leading to enhanced efficiency of 3.22%, whereas a pristine sample showed an efficiency of 3.04%
