A new PiFM application paper was published in “Nature Communications” by Chenkai Sun, Zhi-Guo Zhang and Yongfang Li, “A low cost and high performance polymer donor material for polymer solar cells.” (doi:10.1038/s41467-018-03207-x) To read more: https://www.nature.com/articles/s41467-018-03207-x
PiFM measurements were taken by William Morrison from Molecular Vista in Nanjing.

In the pursuit of high-yielding, low-cost polymer donor materials for the commercial application of polymer solar cells (PSCs), PTQ10 was designed and synthesized under the supervision of Yongfang Li. PTQ10 shows promise as a polymer donor for larger area fabrications of PSCs, “In comparison with the polymer donors reported in literatures with PCE over 10%, PTQ10 shows the great advantages of low cost (benefiting by less synthetic steps and high overall yield) and high photovoltaic performance.”
