Abstract

Polymer bulk hetero-junction 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 mixed nanocrystals by transmission electron microscopy and electron diffraction.
