In this study, an oriented, strong and transparent multiwall carbon nanotube sheet is used as the hole collecting electrode in polymer solar cells with RR-P3HT as the donor material and PCBM as the acceptor material. An open circuit voltage of 0.49 V, a short circuit current of 5.47 mA/cm 2 , a fill factor of 0.49, and an efficiency of 1.32% have been obtained. Performance dependence on incident light intensity along with other various investigations are presented.read more
