A Polythiophene Derivative with Superior Properties for Practical Application in Polymer Solar Cells
ADVANCED MATERIALS, 26(33), 5880–5885.
author keywords: polythiophenes; carboxylates; energy level; polymer solar cells
TL;DR:
A polythiophene derivative called PDCBT, which has a backbone of thiophene units and just carboxylate functional groups to modulate its properties, exhibits properties superior to those of poly(3-hexylthiopane), the classic polythyphene derivative, when used as an electron donor in polymer solar cells (PSCs).

Quantifying Charge Extraction in Organic Solar Cells: The Case of Fluorinated PCPDTBT
JOURNAL OF PHYSICAL CHEMISTRY LETTERS, 5(7), 1131–1138.
TL;DR:
It is shown that the slower average extraction due to lower mobility accounts for the moderate fill factor when solar cells are fabricated with mono- or difluorinated PCPDTBT, rendering the monofluorinate derivative the most efficient donor polymer.

Enhanced Photovoltaic Performance by Modulating Surface Composition in Bulk Heterojunction Polymer Solar Cells Based on PBDTTT-C-T/PC71BM
ADVANCED MATERIALS, 26(24), 4043–4049.
