Fabrication of P3HT: PCBM bulk heterojunction organic solar cell

Abstract

The fabrication of organic solar cells (OSCs) employing solution processing has proven to be a convenient method to guarantee the fabrication of OSCs at low cost and large-scale production. This manuscript demonstrates the successful fabrication of TFOSC with device structure: poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS)/poly (3-hexylthiophene) (P3HT): [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM)/lithium fluoride (LiF)/aluminium (Al) under ambient conditions. An overall power conversion efficiency of 3.25% and charge carrier mobility of 1.22e-2 cm v s-1 was obtained and PEDOT: PSS was beneficial in improving the charge transport processes in the preparation of organic solar cells.
