Confining blended poly (3-hexylthiophene) and [6, 6]-phenyl-C 61-butyric acid methyl ester
organic solar cell active layers within nanometer-scale cylindrical pores nearly double the
supported short-circuit photocurrent density compared to equivalent unconfined volumes of
the same blend and increases the poly (3-hexylthiophene) hole mobility in the blend by
nearly 500 times. Grazing incidence x-ray diffraction measurements show that the
confinement changes the polymer orientation distribution, suppressing low charge …
