| Research Abstract |
The purpose of the present work is to develop and clarify carrier transport mechanism of self-organized core-shell quantum dot bulk heterojunction solar cells. Bulk heterojunction is an efficient method to generate free charge carriers, and the charge transfer is possible at the semiconductor interface. In the present work, fullerenes were used for n-type semiconductors, and metal copper oxides, CuInS2, metal phthalocyanine derivative, porphyrin and poly-vinylcarbazole were used for p-type semiconductors. Exciton diffusion blocking layers were also introduced and evaluated. In addition, nanodiamond and germanium based molecules were added into the active layers of the solar cells. The novel aspect of the research is to investigate the relation between properties and microstructuresofthe solar cells usingtransmission electron microscopy, X-ray diffraction and electronic structure calculation. The impact of the research concerns the study of the solar cells by means of microstructural analysis, property measurements and theoretical calculations.
