Abstract

Polymer bulk heterojunction solar cells were fabricated and the electronic and optical properties were investigated. C60 and perylene were used as n-type semiconductors, and copper phthalocyanine, zinc phthalocyanine and pentacene were used as p-type semiconductors. Energy levels of the molecules were calculated, and HOMO levels were localized around the main chains of the zinc phthalocyanine and pentacene. Nanostructures of the solar cells were confirmed as mixednanocrystals by transmission electron microscopy and electron diffraction. Polymer/fullerene bulkheterojunction solar cells with poly [3-hexylthiophene] (P3HT), poly [2-methoxy-5-(20-ethylhexoxy)-1,4-phenylenevinylene] (MEH-PPV), and 6,6-phenyl C61-butyric acid methyl ester (PCBM) were produced and characterized. A device based on P3HT and PCBM provided better efficiency, fill factor, and short-circuit current compared to those of a device based on MEHPPV and PCBM. The solar cell with P3HT and PCBM structure showed a higher photoresponse in the range of 400-650nm. Energy levels of the molecules were calculated and discussed.
