Collaboration on PSCs Published in Advanced Materials

PiFM analysis of high-efficiency perovskite solar cells (PSCs):

In collaboration with some leading researchers in high-efficiency polymer solar cells, Molecular Vista performed PiFM imaging on several samples. Transient absorption measurements and PiFM analysis investigated the effect of thermal-annealing on the active layer morphology and photo-voltaic performance of high-efficiency conjugated polymer donors for perovskite solar cells (PSCs.) As a result, these measurements were published in three papers: Chemistry of Materials, Angewandte Chemie and Advanced Materials.

In Advanced Materials, Photo-induced Force Microscopy (PiFM) was able to provide real-spacing verification, “The results indicate that introducing alkyldifluorothienyl side chains to suppress the triplet formation and charge recombination is an effective way for further improving photovoltaic performance of the high-efficiency conjugated polymer donors for PSCs.”

Thank you to everyone who made this collaboration possible! We are excited to see the advancement of solar cell research.
