Enhancing the Efficiency of Air-processed Organic Solar Cells by Pristine MWCNT Incorporation into the Active Layer

Abstract

Organic solar cells (OSCs) with P3HT:PCBM active layer and 0.05% wt. MWCNT introduced P3HT:PCBM active layer were produced in ambient air atmosphere and the effect of MWCNT addition on the cell performance was investigated. We report open circuit voltage, short-circuit current density, power conversion efficiency, and fill factor of 0.5 V, 1.178 mA/cm², 0.69, 0.293 respectively. Reference cells without MWCNTs exhibited lower performance. MWCNTs seem to be a low cost and promising candidate for the improvement of OSCs performance.
