The Effect of Ethanol Treatment of PEDOT:PSS Hole Transport Layer on the Performance of P3HT: PCBM-Based Solar Cells

Abstract:

The Poly (3,4-ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) hole transport layer was treated with ethanol to optimize the performance of poly(3-hexylthiophene) (P3HT): [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) based organic polymer solar cells. Washing out of the insulating PSS from the PEDOT:PSS film by ethanol promoted the formation of a conducting PEDOT chain network so that both the conductivity of PEDOT:PSS film and the properties of P3HT: PCBM-based solar cells were improved significantly.
