Abstract
Efficient organic photovoltaic (OPV) modules and cells have been fabricated based on a blend of poly(3-hexylthiophene) (P3HT) and a soluble C70 derivative, [6,6]-phenyl C71 butyric acid methyl ester (PCBM-70). Power conversion efficiency of 4.1 % under AM 1.5 G were obtained in individual P3HT/PCBM-70 cells. Integrated photovoltaic modules with up to four cells connected in series were demonstrated with a maximum open-circuit voltage of 2.48 V.
