Abstract
Water-soluble regioregular poly3-[(6-sodium sulfonate)hexyl]thiophene (PT6S) and poly3-[(6-trimethylammoniumbromide)hexyl]thiophene (PT6N) have been synthesized and employed both as photoactive layers for the assembling of âgreenâ bulk-heterojunction organic solar cells and as charge-collection layers in a cell with âclassicâ architecture. While the photovoltaic performances obtained with the two aforementioned polymers were lower than the reference cell, their latter use allowed to notably increase the inherent J-V properties, leading to a considerable enhancement in the overall photovoltaic output. The power conversion efficiency of the optimized multilayer BHJ solar cell reached 4.78%, revealing a higher efficiency than the reference cell (3.63%).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
