author keywords: polymer solar cells; thick films; fill factor; fullerene loading
TL;DR: The results suggest enhanced electron mobility and suppressed bimolecular recombination upon increasing fullerene content in thick polymer:fullerene blend films, which are the result of larger fulleren aggregates and improved interconnectivity of the fullererene phases that provide continuous percolating pathways for electron transport in thick films.
