Abstract:We briefly report the effect of film thickness on the performance of hybrid polymer/polymer solar cells that were made using poly(3-hexylthiophene), poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT), and zinc oxide (ZnO) nanoparticles. The ZnO nanoparticles were introduced to improve the electron transport property of P3HT/F8BT blend films. Results showed that the open circuit voltage (V(OC)) was remarkably decreased by adding only approximately 0.5 wt% ZnO nanoparticles though the optical absorption spectr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
