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.

本工作的目的是开发和澄清自组织核心量子点散装异质结太阳能电池的载体传输机制。散装异质结是一种产生自由电荷载体的有效方法，并且在半导体界面上可以进行电荷转移。在目前的工作中，将富勒烯用于N型半导体，金属铜氧化物，Cuins2，金属邻苯丙氨酸衍生物，卟啉和聚乙烯基碳唑用于P型半导体。还引入并评估了激子扩散阻滞层。另外，将纳米座和锗的分子添加到太阳能电池的活性层中。这项研究的新方面是使用传播电子显微镜，X射线衍射和电子结构计算来研究太阳能电池的性质与微观结构之间的关系。研究的影响涉及通过微观结构分析，财产测量和理论计算对太阳能电池的研究。
