ABSTRACT

[6,6]-phenyl C61-butyric acid methyl ester: poly (3-hexylthiophene) bulk heterojunction solar cells doped with germanium phthalocyanine or germanium naphthalocyanine were fabricated and characterized. Photovoltaic properties of the solar cells with inverted structures were investigated by optical absorption, current density-voltage characteristic and incident photon to current conversion efficiency. These germanium phthalocyanine and germanium naphthalocyanine blended as the third component absorbed light with wavelength longer than 700 nm. Morphology of solar cells was investigated by atomic force microscopy, and energy levels of the solar cells were discussed for power conversion efficiency.
