Investigation of recombination process in organic bulk heterojunction solar cells — •Jȩdrzej Szmytkowski — University of Saskatchewan, Saskatoon, Canada — Gdańsk University of Technology, Gdańsk, Poland

The mechanism of charge carrier recombination in organic solar cells is still under debate. Although Langevin model of bimolecular recombination is usually used with success, the experimental deviations from this theory have been observed. Recently, several different scenarios have been proposed for explanation. To make further progress, we have analyzed recombination coefficient as a function of several physical parameters. The obtained good agreement between theoretical and experimental results is promising.
